Had a brain F--- and went from reverse to forward before the motor idled down completely. Thought that I broke a gear pin or something. Had a machanic over and he discovered that the gear shifting cable was misadjusted. he readjusted that and I had him change out the water pump at the same time. Went out with him to test it. Everything running fine.. RPM up to 5000+. then it suddenly seemed like it lost a cilinder. RPM dropped down to about 4000. Checked plugs, compression, reed valves and all checked out fine. So he decided that the carborators needed to be rebuilt. He did that...no difference. Changed out the power pack...the epoxy on mine had rubberized and seemed bad. No change. Then he felt that the fuel pump was bad, so he temporarily changed that out with an old one that he had. Not one bit of change, so we put the old one back. In the last test run, he discovered that if he held the choke button in, the motor would jump up to full throttle and stay there as long as he held in the button. As soon as he released the choke button, it would fall back to about 4000 RPM. He still thought that it was the fuel pump. I then had an family emergency and had to leave the state for a couple of months. I called him, but he hasn't shown for about 6 weeks.
Am I over looking something simpler, like a bad fuel return valve, bad bulb or something like that? I am not totally imept around moters and would welcome any suggestions. I sure would appreciate any help.
