I just purchased a used f90txrd. Currently it seems to randomly miss during Idle running on a garden hose. checked the fuel filter, spark plugs, and compression (195/191/199/197). tried squeezing the fuel ball when motor is in idle with no difference in effect. engine starts to run smooth if throttle is increased. currently do not have the correct tach for the motor will the tach from a 98 50hp yamaha (has an adjustment dial on the back) work as it wires into the control and does register rpms (not sure how exact it would be.). Any suggestions would be helpful.
Currently I do not have the diagnostic cable or software for this motor so I can't provide any of the onboard diagnostics as of yet.
Tried different gas as well.
