Yamaha 40 problem
Have a problem with a yamaha 40 , 2 stroke , 3 cylinder 1995 tiller
it is droppin down onto 2 cylinders , wen i go full throttle it runs perfectly but then there is a loss of power after a while and wen i throttle off it comes back , happens every now and then .
i took the sparks plug out wen it happened and none of them were wet indicating it was a coil goin down , i have 2 water filter seperators on , so it not water getting into the system.
i have also replace the fuel pump diaphram . there was no water on the vacum side indicating that the crank shaft seal was gone .
was thinking of getting a new coil and changing out one at a time to c if it was a coil issue
is there a rev limiter on this engine ?? is the cdi a issue ??
need some help in solving this one as its quite annoying wen it happens
