Harrison P: Now I know that the plastic thing, is an air vane governor.
TRUx Voodoo: Fnaguitarplayer, I have a quick question for you: I have a 3.5HP briggs
that looks similar to this. (It's a 1988 model 90702 3080) I just replaced
the coil and I can't remember how the ground wire was set! It won't
restart for me and I know I have it in the wrong spot. On my old coil, one
wire was cut and I think the second one was hooked up somewhere on the
linkage. I've seen videos where they talk about a wire being ran down under
the flywheel, but I'm pretty sure that's the one that's cut on mine. Here's
a link to the image, I just had it contacting the metal bracket where the
fuel hose passes through but I know that it was wrong now.
Karl Kerbrat: Thanks for the videos there very helpful. My uncle gave me an old 3.5 b&s
for my new place and it needs a little work. Its missing the rubber 90 that
leaves the left side of the carb and goes to the air line to the engine.
What is that for ? Been looking up all the videos i can and its just been
mention a bit. Any help is appreciated.
Ron Holder: Someone gave me a mower that has has a Briggs & Stratton engine with this
governor/throttle assembly, or one very similar. The linkage was missing
when I got it, but I improvised with a paper clip. I'm not sure the spring
in there is the correct one; it seems too loose. Some diagrams I've seen
look like there should be two springs, and the throttle bracket itself
looks like it would accommodate two springs, but I only see the one in your
video. I want to order the correct parts so it will work the way it should.
Any more info? Thanks for anything you can share.
acinomed: Thank you so much for this video. I didn't have anyone around to help me
today & mower stopped running right after going under a tree and it had
always run kind of slow to be honest. Had no idea what the governor looked
like. Got it all fixed up in no time. spring had come off completely.
nonutsnorris: Hi.. Mine runs too fast and wont slow down! how do i fix that !
Greg Cherry: TY for vid on gov vane . I hav a prob , 3.5 B&g push , it will idle fine
but when i throttle up it dies instantly, any ideas, ran fine for bout a
Arvind Mallya: Thank you so much my spring was loose and flopping around, this certainly
helped me understand.
Tiffany Chance: My mower will start then shut off. Do you happen to know any reasons for
this? I have a Briggs and Stratton push mower.
jayden rogers: i have an old rover easy start 35. the issue is that it is quite the
opposite to easy starting. i have to tip fuel into the carboy and pull at
least 5 times to get it started (pardon the pun). Not sure if its the
primer button not working or something to do with inlet, but once its
started it runs fine, doesn't miss and never stalls
Veejee: Where can I find the plastic arm that the governor/spring hook into? It
got broken and I can't find one anywhere.
jamesb72: Thanks so much, mower running slow, and couldn't work out why, this is
great help !
rs71355: Thanks for explaining that i wondered how it worked. I have a push mower
with a briggs 6hp motor and its about 18 yrs old but still runs strong.
Last year at the end of season it started revving up and down like the
governor was pulsating, it starts out small then builds till it goes dead &
would not start until it sat for a while. I tried cleaning the carb several
times and would run fine for about 10 minutes then do it again, so i
thought i'd put a new carb on it. I just put it on and it ran great for
about 30 min. then did the same thing so i'm thinking something to do with
the governor now maybe but didn't understand how it worked. Any thoughts on
a problem like this. Like i said it started out of the blue last year. Any
help would be greatly appreciated.
michael williams: hello sir i have a 3.5 briggs i checked the compression and got zero
pressure but the lawn mower cranked up and ran any way could you please
tell me what im not understanding here. thanks Mike
T Pope: EXCELLENT You don't know how much time, effort & head-scratching this video
will save me- Clear concise information & I think very helpful. Nice one
fnaguitarplayer9: are you running it with a blade? if the blade is off of it they will kick
back really bad! my engine here in this video has a heavy flywheel on it so
i don't have to run a blade on it. but if you are running it on a stand
like this, don't run a blade! use a old deck to test these motors with
blades. thanks for watching!!!
fnaguitarplayer9: well i'm glad to help out! i noticed you subscribed, thank you. I'm a
little slow on uploading new videos right now (i'm not at my garage until
warm weather gets here, which it is now haha) so stay tuned for new videos.
Damian Towler: great video. the throttle mechanism had me beaten. i just couldn't believe
that the arm mechanism on the carby was indirectly controlled by the
throttle cable via a spring and a wind vane mechanism. amazing.
and...yes....very confusing. great stuff. good man
fnaguitarplayer9: Glad to hear my videos have helped out! First thing i'd check is revving
the motor up by the linkage just to rule out a carburetor problem, just
move the linkage where it hooks on to the carburetor, if it revs up good,
the governor spring may be installed wrong or stretched, if it still
doesn't throttle up bypassing the governor, then its probably in the carb,
either out of adjustment or needs a new diaphragm, when revving it up like
this, don't hold it high speed. thanks for watching!
reincarnatedman: Thanks for the explication, I've been wondering why my '35 spends time
rising and falling when I start it. Now I'm off to put in a new cord,
afterwards I can re-tension those springs and it'll be as good as new.
Well, kinda ... Kind regards, Light.
fnaguitarplayer9: I hear ya! Glad to help out! Always glad to save someone money!!! thanks
janabeller1: I'm a chick with little mower knowledge and you just saved me a repair
bill. Just now fixed it myself and runs like a million bucks! Thanks!
fnaguitarplayer9: Hey, it should be on the front of the flywheel shroud/cover above where the
spark plug is, if not it could be on the side of the shroud above the
muffler, anywhere like that on the flywheel cover, it will have a model,
type and code. thanks for watching!!!
Andrew McEwan: Ya there great when there running if it is one I do not see a 2digit number
beside the model number thanks for helping sorry that I gave you a tecumseh
to try to help me fix :-) if you want I can send you a picture of the
sticker on the mower because when I typed the model number in to Google I
got 0 results :-(
fnaguitarplayer9: oh ok you just need the bolt. got ya! i've done that before, but it was so
tight that i actually broke the carburetor itself!!! ... i'm trying to find
a diagram for that, but i'm having problems there should be a 2 digit code
after the type, I have probably 300 diagrams on my computer but thats not
on it, so i have to go to briggs website which has changed and i have to
have a 2 digit code. Ran into the same problem earlier with another engine
fnaguitarplayer9: Heard that! I ran into this a while back on a 5 horse briggs! Its the last
thing you think of haha your welcome, Thanks for Watching!!!
foreverwood1963: A lot of hunts and surges are caused by dirty carbs versus bad governor
Mark Almand: I have aYard Machines mower. It has the primer bulb style Briggs & Stratton
6.0 HP engine with a side mounted carborator. model # 123K02-0195-E1 Do you
have a video on how the linkage works from the throttle to the carborator
choke lever? Thanks Mark
fnaguitarplayer9: Sounds like the throttle cable is broke or came loose either at the
throttle control or where it connects on the carburetor linkage, have
someone move the throttle up and down and check at the carburetor to see if
the linkage is moving, another thing, the cable clamp could be loose on the
front allowing the whole cable to move. Thanks For Watching!!!
fnaguitarplayer9: no problem! glad it helped. i've had that happen before, a linkage gets in
a bind or something that makes it stick haha thanks for watching!!!
M Romero: Help! I have a Briggs and Stratton Tru Cut (91232 1253 E1) that I took
apart the carb and can figure out how to reattach the govonor and throttle
linkage. Can you help?
fnaguitarplayer9: i would but i don't have a 4 horse, not sure if its the same as this one.
it may not be on right, i had this problem on another push mower engine,
checked everything then i seen i put the spring on the wrong part of the
governor arm haha it could be a bad spring too, if they get to stretched
they won't work. Thanks for Watching!!!
Bill Perry: I had the same problem as rdwngfreak. After trying almost everything I
could find online, I finally paid attention to "could be a bad gas tank
cap". Replaced it w/ one off another mower and it ran great! The gasket had
gotten deformed. Thanks guitar player for the great videos!
fnaguitarplayer9: No, I don't really have any videos on newer equipment, I do have one on
linkage on a briggs 13.5 horse (same as a 12 horse), which all linkages all
use the same principles, so you might be able go by it, it has the auto
choke, when you give the engine full throttle it hits the choke, so that
might help you out, i'll send a PM with it attached... Thanks for
fnaguitarplayer9: @BoscoeFrance thanks! i hear ya. i do alot of guitar modifications and hope
to start building from scratch. i love tube amps, i always wanted to build
a fender twin reverb amp. glad the video helped! thanks for watching!!!
fnaguitarplayer9: Your Welcome! Always glad to help out! Thanks for Watching!
Jim Wisneski: Thank you for the awesome video, you have helped me to regulate my
screaming Briggs which I thought was going to blow up!! Now I am back to a
NORMAL RPM and can see many more hours of usage. Thumbs up my friend!
fnaguitarplayer9: hahahaha thanks for watching!!!
fnaguitarplayer9: sometimes you just can't adjust them out, hate when that happens. i got
several of these motors that need carbs rebuilt, reason i haven't is i just
don't need them all running, i'll fix them when i need them haha yeah that
should be all it needs. no problem, glad to help, anytime!
fnaguitarplayer9: send me the model type and code off the engine and i can look up parts for
you. thanks for watching!!!
fnaguitarplayer9: its probably a older one. briggs website is almost useless for looking up
older engines, luckily i have almost every parts diagram for them. yeah
sure, i'll pm you my email!
gary tennesen: HEY!! Just wanted jump in an thank you for your video!! I have been trying
to figure out what to do with a B/S 3.5hp that surges and stalls "if" I get
it started. Your video showing me what was under the cowling (the flywheel
areas) gave me the courage to get out there and give it a shot -- I work on
computers BUT needed your video to show what was under the hood of a small
engine. FIXED. Previous owner installed choke/throttle upside down
PunaniLicker69: hello kind sir. can u show me with a video how to slow down the engine on a
4hp b+s engine? the springs that i have do really do anything. there is no
give or pull. why is that? ty.
fnaguitarplayer9: yeah there is some differences between them, i will do that, just got to
check my engines to see if i have one with the different setup than the one
in this video. thanks for watching!!!
Bang Arang: I found this video very helpful. My springs sprung this morning, leaving my
fly-wheel vane flapping in futility. Your simple explanation helped me put
the proper names with the parts I'm working with.
Justin LaNoue: Funny this reminded of when I was around 9-10 years old had a 3.5 hp and it
was constantly revving up and down over and over...I couldn't figure out
what was wrong so I just bent the gov all the way open and stretched that
throttle spring all the way out. I was pretty much red lining that poor
little motor and it went through 2-3 spark plugs per season, but it kept
going for years. And I never came across grass too thick to plow through at
1972FordF150: I just made a video a lot like this LOL
outdoorsman310: this is the same design as on my 1960s briggs before i broke the air vane
fnaguitarplayer9: @outdoorsman310 this is a 78 here. haha never seen that happen before haha
thanks for watching
fnaguitarplayer9: yes and no, no because unless you rebuild it with racing parts you will
blow up / destroy the motor, its not designed for those high rpm's. You'll
be surprised how much power it will have governed, and if you gear it right
it will go pretty fast. Remember that all stock go karts come with a engine
governed at 3600 RPM, same as a lawn mower engine! thanks for watching!!!
