Man, this 17 hp is driving me crazy..... So wierd. Hate to bother you (anyone feel free to reply), but you've always been the resident expert machanic, so....I hope you don't mind.
This question could pertain to any 4 stroke engine.
What could make one cylinder (a twin in this case) run so lean, and the other is burning perfect. I could see if both plugs were lean, or if each had their own carb. Just started doing it (will drop about 600RPM.....or be fine) Takes along time to come up to 3200 RPM (high as it will go) under laod (3650 usually underload)
Seems like with the compression the same on each, it would mean that the valves are seating right (but does "spit" alittle mist of gas out........and I was wondering if it was getting around the intake valve from the combustion chamber.....) normally I would say timing.
Starts great, and runs great, just low rpms, and no power when deck engaged. (I know power = compression....
Bottom line, I can put in a new plug, and with-in 3 mins. it's white.
Don't want to run it with that cyln. that dry/hot. Anything you might could think of that would make a plug lean out so bad so quick? (need it running bad)
Might get a 23hp Kaw just and worry about this 17 hp later.
(Thanks Hoss)
(all started after the carb./airbox got loose, and was sucking much air (15 mins. tops is all it ran)
