I got an old evinrude 33hp 1965. It has new w impeller new cylinder head gasket new sparkplugs new fuelline carburator is cleaned.. It started an ran pretty nice for a moment then it started to lose power so i had to choke it to get it runnin, but then it just died and now it doesnt start. the compression is 92psi on both cylinders when the engine is cold. god spark on both sparkplugs. the upper is a little better than the lower. Please help me i planed to test the boat (3.8m sportboat) soon as posible...<br />/Kim
