I strongly agree. I was just curious about the igniter distance issue. The orifices on these motors are so tiny they dont have much of a chance of remaining clear unless the motor is maintained well and the owner is aware of what it takes to keep these motors in running condition.. Just my opinion. So the tether switch was going bad and replacing it fixed the spark issue but it still ran terrible, surging, stalling, then running great. Shut down then hard to start. Had the carb off a few times. Cleaned it as well as the fuel lines, flushed the tank, made certain there were no leaks, made sure the fuel on off was working properly. Custumer did not tell me he had gone into the carb and had broken a thin peice of wire inside of the main jet up through the nozzle. It was broken in such a way that you could not see it . I used a jewelers loop and bright light to catch a reflection of it. I tried to grab it and pull it out, wasted time on that method.Finallly blew it out under high pressure. Motor runs great now. Another problem solved thanks to the IBOATS forums and its expert advice.. Thank you .
