" my carburated 80 hp 4-stroke
" my carburated 80 hp 4-stroke yamaha is losing power at high rpms (over 3500)_relative to the other engine.
white smoke also starts to come out at high speed.
less than 3500 rpm, the engine runs perfectly. perhaps it is some crud in the high-speed jets?
any thoughts would be greatly appreciated.
aloha, rob
p.s. the problem seemed to start after i filled the tanks with yellowish colored gas (as opposed to the usual clear). i checked the separator and no problem there. i added sea foam gas treatment.
the battery also died the day the problem started. i changed both batteries, as well as the spark plugs. they both run perfectly now, except for the one engine at high rpms. "
