Engine starts fine, runs very smoothly with good power. While under load it will suddenly quit, Sometimes if you pull the throttle back quick enough it will be idling. Most times it starts again easily. Sometimes you need to squeeze the primer bulb and it starts. Occasionally it won’t start until after 20 to 30 minutes and it is seemingly running just fine. Vexed by this problem, any suggestions appreciated.
