Hello Robert,

That is normal only if you fly on weekends only, on consecutive days it should not happens, but your priming method might be the problem.

With the ignition off obviously, open the throttle fully, move the prop by hand slowly until you hear the engine "click", then move the prop back and fourth with your hand quickly until you see the fuel on the hose running into the engine, the engine will not be flooded, unless it is done excessively, then go back to idle, ignition and the engine should start immediately.

Check the fuel hoses and the reference hose to the regulator also, this reference hose I change twice a year no matter the condition.

Good luck

Alejandro P.
