Re: Ironhead carb issues?
If it only starts to squirt at 3/4 throttle, it's your accel pump.
Try this. Clean your plugs first, take your air cleaner off and grab the throttle lever on the left side of the carb with your left hand, on the right side of the carb put your thumb on the end of the accel pump shaft where it meets the throttle shaft. Now move the throttle shaft open with your left hand while pushing down on the accel pump shaft and watch to see if you have a full stream of fuel. If you do, crank it 3 times this way and it should start. Then you can ride it over to the mechanic and tell him your accel pump ain't working.
