I have a problem with the engine loading up if I idle for too long like while a skier is getting ready for too long. If we are cruising around from 20 -40 mph then stop and idle for a second then hammer it then it seems ok with a slight hesitation. However if we hammer it after idling for too long it will kill the motor if you hammer it to pull a skier up.
Some background, I am pretty new to boats but handy in the way of cars. I just got this boat and the guy said he rebuilt the carbs. I found the timing to be way out of adjustment so I set that up the other day and have the carbs adjusted at 1 or 1.5 turns out. I also noticed the priming bulb has a pinhole on the engine side of it (I bought a new one but haven't installed yet). I also checked the compression and they are all between 105 and 110. My first plan to try adjusting the idle screws at the lake next time we are out. Any other suggestions? do you think this is a loading up of fuel issue too?
