outback65 0 #1 Posted July 12, 2017 Hello, Curious if anyone has attempting converting a Onan P216G to a P220G? I have a P216G which most likely needs some level of rebuilding (1450hrs, low compression on both cylinders - 65psi) and I was curious that if I'm replacing parts, would it be worth the cost of new/used crank, cam, (bearings?), valves, guides, seats, connecting rod, pistons and carburetor for 4 more horse power? PS: the Engine runs on the 416 tractor (w deck), and the package was free. It appears it was well maintained for the first approx 1000 hrs and the 2nd owner just ran it into the ground. I have rebuilt a P220G this past winter and revitalized two other P220G with great success. Sharing of any Onan experience would be appreciated. Tinkering in PA............ Thank you!

chip61 655 #2 Posted July 12, 2017 I don't think it would be worth the time and expense, you could probably find a decent 220 for less money. Unless you want to run a 60" deck I haven't seen where the 216 struggles doing anything I have thrown at it. Share this post Link to post Share on other sites
boomers_influence 106 #3 Posted July 12, 2017 outback if both engines are new, here are the differences. ( 16-20 ) crank, rods, cam and carb. 16 to 18 is only crank and rods. thank you. boomer ( the used onan engine parts guy, also NOS and new ) Share this post Link to post Share on other sites
