Motor stalls

[Doug Shell]

After motor warms up it won't take gas and stalls out. I have replaced power packs,rebuilt all 3 carbs. and rebuilt fuel pump, changed gas line and bulb. The bulb won't pump up tight(bulb is going in right direction).

Re: Motor stalls

It acts like you got a bad primer bulb, unless you have fuel exiting one or more carbs (overflowing), or a plugged pickup. Buying a bad primer bulb is not unusual. There are some junky ones on the market.<br />If you have fuel escaping the carbs, it is the float valve needle hanging open.<br />If the pickup is stopped up,or tank not venting,the primer bulb will go soft,and in some cases even collapse like a cheap straw in a thick milkshake.
