"My 2002 9.9 starts easy and runs great, BUT when I run at idle or very low speed for a while, then turn it up, it runs really rough before it revs up, and sometime it dies when I give it more throttle.
As it speeds up out of this condition, it acts like it's maybe running on one clyinder, then the other cylinder kicks in.
I haven't even had a chance to check the plugs yet.
The engine sat for about 8 months, through the winter, without any special attention. It has run maybe 10 hours since then, sometimes for 3 hours at a time, with no problem except the low rev to high rev difficulty.
Where should I start?"
