Correct. Just for the startup I left the sheilds off the bottom . The front shroud is enough for a short run. The final assembly had all the sheilds installed
You build these Onan engines? Do you have a website or contact info? I’m building a few and always looking for parts - like exhaust tubes for the CCKB.
Unfortunately I only buit 3 of them after I found one and then bought a bulk lot of 4 engine in rough shape that needed some work. I had to order all the parts on ebay. Exhaust components were the hardest to find because the steel seemed to thin for use as headers.
parker stutsman yeah :) it’s such a dumb thing to get stuck on too so unless you have a welder, pipe bending skills, and the tools to cut the flanges it’s a major pain. I’m putting a points box on now and it’s so unclear how to adjust everything to get it right.
Have same motor needs rebuilt it smoke trew carb cut grass then lose power then throw it in neutral builds up power cut some more then same lose power trow it in neutral it builds back up on and on is it rings
Do they sell performance parts for these so that I can get rid of the governor eventually I want to do a mud mower build on a sears suburban garden tractor and if it comes with one of these I might want to do a performance build on it to save a little money
I belive the motors are very reliable, they are simple and built well. They used these engines in kit aircrafts. I've seen many people say they get 1750-2000 hours. The issue is lubrication of the cylinder walls. Being opposed and laying on the side rings wear out and can cause cylinder wall wear.
Actually im in the process of putting an onan engine on a gokart, big issue with mine is the driveshaft is 1-1/2 inch in diameter and the biggest clutches and torque converters only come in 1 inch diameter. So as of right now im seeing how id run a jackshaft with a torque converter.
im kinda late seeing this video but you mentioned not installing the shields i believe these are necessary for the fly wheel to route cooling air across the heads etc.?
I've rebuit 2 and restored parts for sale. I haven't done them in a while now. I have a miata I'm almost done with and 2 polaris ATVs that had engine rebuilds now. If you believe the engine has just typical wear then it would be good to rebuild. Its when you have to buy a new block that the choice is hard. I'm not sure I am ready for another project just yet.
Is that the same one as the onan performer 18 xsl see I don't know because it didn't have one side cover to it just the front cover I need to know if if uses points or a condenser on the coil My onan gt 19.9 does have points and a condenser but not the 18
Parker, I have a P224G that ran fine before it lost compression. Reworked the motor put it back together and I do not get ignition. I have spark, compression and fuel but no Bang. even with starting fluid it does not run. Do you think I have the timing off? I am reasonably sure that the timing marks where lined up on cam to crank. I will double check but any other ideas please ?
@@parkerstutsman7181 pickup at the crank shaft. I have taken the plugs and zip tide them to the muffler pipes. Crank it over and both plugs have spark. I see plenty of fuel at the plugs.........
@@vincentprocaccini i feel like it has to be due to timing. But one thing about these engines that you won't notice easily is if the cank and cam are not timed correctly. Its easy to tell by taking a head off and turning the engine slowly. If you can clearly see each stroke and get to the ignition pickup point on the crank just before top dead center with both valves closed you can verify you are close. I would be willing to say you may be seeing ignition just before your intake at the end of an exhaust stroke.
@@vincentprocaccini also reason I say its hard to notice is because your valves will never impact the cylinder head which makes this a great engine to learn to rebuild. Hard to really damage much.

I just started rebuilding ONON engines. Amazing beefy engines... Working on a B48 P220 20hp opposed twin for a friend. Challenging complete rebuild...
Make a video on how to check the valves on a onan 16 if you can
Nice.
Whats the chance that you have the wiring diagram for one of those? I have a t260g that I need to get running.
Are parts still available?
including the one on the bottom of the oil pan

I have an onan performer 24xsl but is there any good site for engine parts like valve springs etc? Exhaust parts not that big of a deal for me.
I have a miller welder with that motor with 1290 hours , question is that a good motor, and how much lite is left in my motor in your criteria
Life not lite

Change oil and filter and air filter and do maintenance and take care of it and it will outlast you
That's a neat little engine. It's like half of a Volkswagen beetle motor. I might build a utility vehicle for the backyard with one of these.
Or an ultralight aircraft. That's a good motor to use.

@@absolutelyphucked150 A torque converter? That would have to be one heck of a go kart. Sounds like you're putting an automatic transmission in it.
@@Cat-fy5lw these engines are heavy duty cast iron and weigh a lot not running fast enough or light enough for an aircraft
Is there a way I can get into contact with you I think I got a 60s onan sureweld welder and I have some motor questions. Thanks
Do yours idle high
Do have a B43G Onan 18 hp for John Deere 318
Where are you located
What size is the shaft on these
1.25
mine is 1-1/2, i also think i have a different onan engine though.
The p series’s have usually 1-1/8
How much are you selling on an engine.?
I sold the fully built green motor for 850+shipping. Which was less than it should have been but I made some money.
im kinda late seeing this video but you mentioned not installing the shields i believe these are necessary for the fly wheel to route cooling air across the heads etc.?
Have you rebuilt any of these engines? I have a p218g I’m possibly looking at getting rebuilt

parker stutsman yeah the blocks good just needed pistons rings and the cylinders honed. It smoked
I am guessing this as an 18 horsepower ?

Does it use a pickup at the flywheel or points like my engine?
@@parkerstutsman7181 pickup at the crank shaft. I have taken the plugs and zip tide them to the muffler pipes. Crank it over and both plugs have spark. I see plenty of fuel at the plugs.........

parker stutsman copy. Thanks so much for monitoring your site. I will give it a close look. Thank you
Do u have a p20 for sale?
Unfortunately not sir
