what is normal nitro engine life?
i understand there are alot of valiables to this question but i put an lrp .28 spec 3 engine on my losi 8t truggy, broke it in properly (another argument), ran it very rich for about 1 1/2 gallon. then race tuned it ( seemed to be perfect tune & tune didn't change until problem occured) & ran it pretty hard on track with buddies for about another 2 1/2 - 3 gallons ( about 4 gallon total) when all of a sudden it started stalling upon throttle release(when warm). i did have the clutch bearings go shortly after & changed them with no change to running. it does still run strong other than that. (very annoying stalling after 1/3 tank). i did alot of research on this site for answers & only come up with motor getting weak. i tried sealing engine, retuning & every ajustment i could think of. i did just order another motor but was wondering what to do with this motor? should i try to replace piston & sleeve? (not cheap). or just scrap it? or maybe i did something wrong? any insight would be helpfull. thanks in advance.
