[QUOTE="Russell, post: 43314, member: 291"] I just replaced the head gasket on my machine after it rusted through and squirted coolant all over the exhaust manifold. Fortunately, there was no breach into the crankcase or combustion chambers. I believe I followed the instuctions in the repair manaual correctly in re-assembling, but it does not want to start. On page 7B-49 there is the discussion and sketches re: timing belt. I found the timing marks on the camshaft pulley and top cover easily. In picture B it shows how to line up the timing marks on the crankshaft sprocket. The sketch isn't exactly like my engine, so here's first question--the sketch shows a pretty fine pointer attached to the engine case, and a pencil -size timing mark on the sprocket. On my engine the pointer is more substantial--it's part of the casting, about 1/8" in diameter. Location is the same as in the picture. The only mark I could find on the crank sprocket was a tiny dimple like a punch mark--not very substantial, but all I could find. Are these correct? On page 7B-4 there is the description of how to time the engine. It describes a notch on the crankshaft pulley. I am accustomed to seeing these notches on many engines, but there certainly is not one on mine. All I have is the little punch-prick described above. Is this the timing mark I should see with my timing light? [/QUOTE]
