This is a 98 model which I have had since new. It probably only has < 50 hours on it and gets run about 4 times a year. It is pushing a canoe. It runs OK until half throttle or greater. It will then run fine for a few minutes and then start losing power/rpms, then regaining then losing... all in about 2 seconds time. Sometimes it will cut off on me after this rough running, after which I can just crank it again. And then sometimes, but rarely it will run OK at this speed without probs. It almost seems like a fuel flow prob, internal tank, or possibly a carb issue. The engine does not seem to be running hot during these episodes. <br />Do I need to attempt to disassemble/clean carb? If so, could you advise on what you recommend. Thanks much.
