I have a 1990 200 Johnson and have a little problem. I got it off my brother and he told me the last time he used it a couple of years ago it would miss from time to time. I took the boat out the first time and it ran terrible, wouldn't plane out, ran like it was at 1/4 throttle or something. It opened up and did fine for about a mile, then back to nothing. I drained the carbs and all looked good, changed the fuel filter (he had been starting it and running Sta Bil thought it each year) took it back out and it took off great...for a while, then it started again, but it did it much less this time only acting up for a couple of minutes. I am thinking that my primer is sticking and flooding the motor. I noticed about 1/4 cup or so of 2 cycle oil in the air silencer cover and also the spark plug gaskets were saturated in oil (running premix now) the first time I took it out. I have worked the key and listened and the primer always seems to click when I let it off, but of course there isn't a load. The weird thing the last time it acted like this I figured out I could turn the motor off and restart it and it would run fine, like something had been stuck and just needed reset. Thats what got me thinking primer. Ideas? Thanks!
