    My engine cut out after about 2 mins run time. Engine was sitting hot before starting. Ive noticed fuel pressure drop off a couple times after starting up when engine is hot. Im picking that the fuel is being heated in the fuel line where it runs accross the engine rather than in the float bowls as the motor will run for some time before cutting out. Im looking at moving the fuel line as far away from the engine as possible and heat shielding it I also have a check valve I can place inline between the fuel pump and the carb. Am I on the right track with this fix or should I be looking at other options

    It seems a bit strange since you have no engine cover and it wasn't that warm where are the lines and fuel pump, I wouldn't have expected vapor lock but if it was then it will be bad during summer! 8O
