" Thanks in advance for any help given!
Let me try to give a little info first to help in the diagnosis.
The motors are 1989 140HP V4 OMCs. Engines run off of common fuel supply, seperate fiters and primer bulbs. One starts and runs fine, other is hard to start, stalls sometimes both in gear and in warm up @ lower rpms (>1500) occasionally will stall at cruise, not very often. Motor will not take throttle until it runs for a while (5-10 mins) whether warm or not. Motor will not start well warm or cold. I have not done any checks at all. the only thing I did was replace the plugs. Didn't make difference but I looked at them and they seemed to a alot of wet carbon on the port plugs. Sounds like fuel to me. VRO? Carbs? Compression reads aprox 92 Psi, which I understand is ok on this motor. Once motor is up and running it seems ok until you back down the throttle.
Thanks
