Philscbx: Soon as the Onan is done, the Honda for sure is going in. I'll bet it uses
less fuel as well. I used my laser temp gun to see how hot the engine gets,
even blown super clean with 200 mph blower, and the temp was 285. Thats a
bit too hot and why it's so critical to keep the oil clean and full. I also
use the best toughest oil for this, 20/50 Castrol racing oil that I use in
my Honda 1800 VTX. Trouble with good oil is now this dam Onan will last
jizzmonger: @PnKAllen They were good for 800 hours and that's about it.
mondo78: This engines are built to run that hard. The faster you get the blades
spinning the better the cut. My Dad was the same way he never ran his 317
at wide open throttle (WOT). Since I have been mowing his lawn I run it at
WOT and for some reason it also uses less oil that way.
slowride55: sounds sweeeeeeeeeet
triplex4286: I got a 15.5 toro wheel horse but its not full throttle unless im mowing
and that thing cuts so good and it can do 360 turns and it was made in
1995!!!!!!! that thing rules its a hydostatic and it can mow down 3 foot
weeds with no probs I'm going to try and put a vid of it up soon
Benjamin Schlechter: What kind of engine does the JD 420 lawn tractor have? I've heard it has
the Kohler, but not sure. I always thought the 318 had kohler.
UTubeMeTubeWeTube: I've got the same tractor with the 18 HP Onan. Did you have the Onan too?
How do you like the Honda compared to the Onan?
mondo78: I don't know how many times I have watched this. That engine is music to my
dondawg00: @JDMowerMan1998 When your cutting grass, always mow with the engine wide
jizzmonger: @JDMowerMan1998 Blade tip speed matters for cut quality and best bagging.
Always full throttle for mowing.
Robbie Neufield: nice honda engine my friend
Dick24319: WOW!! We have lift off it sounds like!
dondawg00: @benschlechter The 400 has a 20hp kohler, the 420 has a 20hp onan
Todd King: My 318 Onan has a little over a 1000 hrs on it and a rod is just starting
to knock. I don't know whether to try to fix it or repower. Some parts are
still available for the B43G, I have the skilz to fix it and I love the way
it runs so I'm having a hard time thing about moving to Honda power.
PnKAllen: Yes mine had the Onan also. The Honda has more power and is more
responsive. If your Onan is running strong and not using any oil, keep it.
I replaced the Onan because it was flat worn out.
PnKAllen: Anybody that knows anything about small, air cooled engines, knows that
they are meant to run at WOT or aprox 3600rpm while the PTO is enguaged.
Mainly this is due to the engines air requirements for cooling. Not to
mention that higher blade speed on any mower deck equals a better cut.
Jim S: Actually, the main reason small engines are designed to run at WOT during
maximum (full) load are economical. Sizing an engine with little/no spare
power means less costly engines and a better bottom line for the company.
Attachments such as decks, snow blowers, tillers, etc. are designed for
peak performance at rated RPM. Small engines arent designed to lug. Load is
the greatest contributor to heat and a smaller than rated load will create
less heat and therefore a smaller need to dissipate
PnKAllen: Small Engine Warehouse, $1700.00 and a 2 1/2 hour install. It's a direct
bolt in kit.
jay600katana: is the honda good on gas? Any trouble with the install? My Onan is almost
dead but I'm going to blow that bastard up first (not seize, rod threw
jwalters25: That tractor sound reborn with that Honda in it. My parents have a 318 with
the Onan; it is worn out! Did the Honda mate perfectly to the frame and the
electric clutch or did you have to make madifications? What is the model
and serial number off the engine?
1944johndeerel: how bad was that conversion? not bad results though.
flanksteak2: @PnKAllen Better to think of the throttle as setting engine RPM rather than
actually moving the throttle plate.
tractorboy8420: oh that sound brings back memories! i loved our 318! i miss it so much! but
he had to upgrade to a Kubota L3430 instead.... its a great tractor too
withits rear mount woods rm990 but still.. i miss our great 318! it was the
