mikekot3 92 #1 Posted July 18, 2015 My Toro 416-8 with an Onan P216g engine is burning a lot of oil like 1/2 to 1 quart per Lawn mowing. It also has small oil leak under a shroud near the starter and cylinder head area.The muffler was glowing orange I am presuming from unburned fuel as it runs rough and back fires when at operating temp. From what I have read the ignition module under the flywheel is a common failure for poor running/low power.I blow out all exposed fins every time I finish using the lower. It has about 800 hours on it.Please advise,mike Share this post Link to post Share on other sites
boovuc 1,090 #2 Posted July 18, 2015 If your muffler is glowing, your fuel mixture is real lean and that also causes poor running issues as well as a very hot engine! Your ignition module is most likely fine! You need to adjust your fuel mix to give it more gasoline and I wouldn't run it the way it is running now. 1 Share this post Link to post Share on other sites
cleat 5,000 #3 Posted July 19, 2015 Giving the carb a good cleaning should help. Main jet could be partly obstructed causing the lean mixture. 1 Share this post Link to post Share on other sites
Fordiesel69 228 #4 Posted July 24, 2015 This is a quick way to loosen or burn your valves / seats. Adjust or clean the carb. Share this post Link to post Share on other sites
mikekot3 92 #5 Posted July 26, 2015 Hello everyone, I used some seafoam fuel system cleaner down the orifices in the throat of the carburetor which seemed to help. I may still need to rebuild the carb. Share this post Link to post Share on other sites
