I got to wondering if I could be having a vacume leak at the heads. The intake/exaust gaskets have a square opening and I thought it looked like the round intake manifold openings would seal off. Now that I think about it I am thinking there might be 3 round gaskets made of the gasket paper in the set. Could that be the place for them? If so I should have known better!!!. Also I wired a plasti bag over the air cleaner today with the pre cleaner renmoved and it sucked down on the bag. I also took one of the plugs out of the intake manifold and when priming gas was going up into the manifold. But I do notics I cannot smell ether or lp on the plugs. I also pulled the front off the reg and the valve releases gas freely. I am thinking I ether have no fuel getting to the cyls or very bad timing or both.....
