I dont know why I did not throttle up the engine. I tried it today and there is vacuum there with engine throttle up.So the vacuum hole must be on the top of the throttle plate. I guess I was thinking of 60s and 70s cars when you pull off the hose for the vacuum advance there is vacuum there even at an idle.I put a small hose on the vacuum advance with distributor cap off and i can see the breaker plate move and it holds vacuum. Also checked the mechanical advance it moves and returns as it should.
