Small Engine Problems? Ask an Engine Mechanic for Answers ASAP
Thanks for your response. I fitted a new cylinder head so had ruled out valve seating problems but checked it anyway. On rotating the crank slowley I notice that the exhaust valve lifts very slightly on the compression stroke, this is caused by a small metal shape mountred on the camshaft between the gear and fist cam lobe. could this be the cause or is it part of th easy start mechanism?
