Hi DANO, so you can appreciate that the problem exists with the hot engine so in my opinion it is related to dilation of metals or components, in your place I would first lead to measure the compression of the cylinders since a leak in the lid or if you have the joint of the burned cylinder cover in cold again. Then you tell me

Hello, how do you thank you for your comment and if you effectively check comprehensive to each cylinder is between 85 and 90 psi. But notice that Occasionly also being cold the engine has presented this problem and the checked of the two forms and I have fuel but there is no spark in any spark plug.
