I have hit a wall and need help figuring out my problem. I recently bought this motor knowing nothing about it. It starts fine and idles good. There is a miss at all RPMs but not always. When I throttle it all the way up it has lttle power, the RPMs don't seem to come all the way up and there is a miss every so many seconds that almost feels like a boost in power.
I've had the carb off three times. It seemed very clean I ran wire through all of the nozzles and sprayed liberally with carb cleaner. Nothing looked bad. The only thing I did notice was inside the primer button. The diaphragm is dry rotted and falling apart. I cleaned it out and put back together. I didn't think this was an issue because I don't use it. I checked compression and have 90+ on each cylinder. Today I used some sea foam to see if it was a build up of carbon. Lots of smoke but no noticeable change. I changed spark plugs. I did use a different plug than was in it because I read online the plug that I should use and the plugs in it were wrong. I cannot afford to put a lot of money into this motor. I have $800 into it now with the purchase and replacement of two shut off switches. Can someone help?
