Mark Vizer: I have same engine on string trimmer. Even after replacing fuel lines,
primer bulb, air filter and cleaning carb, it only want to cold start with
removing air cleaner and injecting starting fluid. It seems to flood very
easily so when this happens, I have to remove spark lug, clean plug, pull
though a few times and then start
Once started, I runs well at high speed , tolerates load, and idles well.
1972FordF150: @goldsuzy hahahaha what ?
goldsuzy: @1972FordF150 I prefer my 52 inch with the 351 ford V8
Mark Vizer: Thanks, but above my skill level, unless there's a video on that, too. No
chance that adjusting high speed screw would do the trick?
savagenomore: so if I have the same problem but my carb has no adjustment screws what
should I do?
donyboy73: @motorhead45102 check the head gearbox. DO NOT BUY A 4 CYCLE RYOBI! THEY
ARE JUNK IN MY OPINION AND ALL MY MECHANIC FRIENDS. buy Sthil or Echo. not
much more and twice the machine
donyboy73: @pivotboy63 i would put in a new carb kit, have you tried adjusting the
motorhead45102: thats weird, cause i worked on this same thing at work and it doesn't do
that, must be some models have that, or the coil is not wanting to work
right at high speeds, but idk never had a ryobi do that. also quick
question, on a troybilt 4cycle trimmer, it will run fine and rev, BUT the
cutting head does not spin, but the cable in the shaft is? also whats
everyones opinion on a ryobi 4 cycle trimmer? i was wanting to buy one.
snaponjohn100: I stand corrected. I just found a Briggs 699875 that has a built in rev
donyboy73: try a new carb kit
Jeff Speaks Jr: i have the same problem with my pocket bike engine, it is the same engine
and carb as ur stand up scooter. i tried adjusting the mixture screw on the
side of the carb, and now it won't run, what do you sagest i do
Jamie Wood: that dose that thing do??
goldsuzy: Top vid. Very well done thanks.
Joe Mulford: Good job. How did you get it to idle so slowly? My Ryobi trimmer idles
pretty slowly, but the clutch always spins a little. I want it to idle slow
enough so the clutch stops spinning completely. But when it does, the
engine idles too slow and dies.
ringbolt9: cute little thing . be handy too I bet. I hate to get my big one out for
just a little spot here and there. good vid bro
Joe Mulford: @donyboy73 Okay, thanks. I'll take a look at it.
Lakedog: Thanks Bud, worked like a charm on my Ryobi trimmer! saved me some money
too! Much appreciated!
djc213: Thanks for the great videos. You've saved me a couple times.
christopher békési: sounds like it gets to little gas might be the jets
donyboy73: @pivotboy63 check all the fuel lines and on the connectors
1972FordF150: cool video man ! and how come when you full throttle it it sounds like it
has a rev limiter ?
1972FordF150: @donyboy73 That's kind of odd to have on a weedeater engine isn't it ?
Looey Tremblay: dony boy if i pour gas in my carb it runs perfectly, but the fricking thing
wont start, new gas lines and bulb and gas circulates through them and i
1972FordF150: @foreverwood1963 I know it isn't those tillers are just weird in my
opinion. And I prefer a craftsman 26 inch front tine tiller with a 5 HP
Briggs I/C engine. ( it's what we own )
carnivore10: I have never seen one of those. Good video, thanks for posting!
donyboy73: try a new carb kit
donyboy73: @motorhead45102 i tried all that, it does sound like the coil is rev
limited, i still have to talk to the owner and see
th19940305: How much did you charge to do that? Nice work it took like 15 minutes to
repair it, good video too.
Joe Mulford: @1972FordF150 My Ryobi does that too. I've got it set so lean that it just
screams and makes your hands buzz! So for a second it like backs off the
revs a little bit and runs a bit richer then screams again. It's like a
mini rev limiter! Or it could just be 4-cycling a little, but that's good
since I wouldn't want it to overheat!
foreverwood1963: @1972FordF150 It's not strange here to have a weedater engine, I see it all
the time. I don't like them though. Prefer 4 cycle engine with tillers.
starkran000: most 2 strokes do that that is normal
donyboy73: @snaponjohn100 a lot of outboards have them
snaponjohn100: 5 stars. I have never heard of a magneto that has a built in rev limiter.
All of the ones that I have heard about are a separate ad-on electronics.
donyboy73: @snaponjohn100 the owner said it did that since he bought it
donyboy73: @ringbolt9 nice and light
Gage Hawke: good job thanks for the information.
motorhead45102: i don't know why but, it sounds like it still could use some high side
adjustment on the carb, cause i know those things can scream higher than
that. and it just doesn't sound right. IDK? hard to exactly determine over
the video at times. but good video though
Frank Parker: Donyboy98, You should start a small engine class if you don't already do
so. You give such step by step instructions in which anyone could follow.
Thanks for all your help. Keep up the great work.
1972FordF150: @donyboy73 And I heard that the recoils like to mess up on them.
Francis Cadullo: i have one and it wont run at all
korthanke1: love your videos.... i have a poulan pro NON adjustable carb on my
trimmer... it is now adjustable thanks to an emery wheel on my BD rotary
tool... the trimmer has NEVER run without 1/2 choke until it's absolutely
hot and now it runs like it should WONDERFUL!!!!
76chyanne: dony boy i have a bolens very similar to this i can get it fired up ,but
when i replace the air filter asembly she will not start,take it off shell
fire any suggestions
donyboy73: @MrMoterKid what usually causes this are weak springs in the clutch
donyboy73: @76chyanne sounds like the air filter may be plugged, time for a new one
donyboy73: @pyrophilster thanks
Dnuccio95ZJ: i got a ryobi trimmer with this same engine same carb and everything.
sometimes it will idle fine, but wont rev up. other times it will rev up
but it wont idle. the diaphrams are good and the screws are fine. i dont
know what to do
76chyanne: i have a bolens like this why is it spiting fuel out the top of fuel cap
any idea what would cause that
xplor nevada: Thanks! My Bolens bl410 cultivator is almost the same & had the same
problem. My Walbro carb screws aren't slotted, so I tapped the high screw
with a smal., sharp screwdriver and a little hammer to turn it an eighth of
a turn. Saved me a trip to the shop!
donyboy73: @1972FordF150 yes it seems to have a rev limiter, i have to ask the owner
if it was like that new
Shannon Locchi: its called a wiper sniper
