Quote: Something is VERY wrong. Did you fix or check the balancer issue?
There is NO REASON that camshaft shouldn't idle at 750-850 rpm with a 50-75 rpm drop in gear.
If the timing is correct, I bet there's a vacuum leak somewhere.
Start with the BASICS - make sure the timing mark on the balancer is not off.
Do you know how to use a positive stop tool against the piston to determine if the timing marks are off?
If the balancer mark is on, is the oil pump drive properly indexed to the # 1 cylinder when the motor is at TDC?
Where is the cam installed - straight up, advanced, or retarded?
Do you have adjustable rockers - if so, are they adjusted properly?
Can you block off all other vacuum hoses and outlets on the manifold except for the vacuum gauge and the vacuum advance for the car, to eliminate all other sources of vacuum leaks?
Can you borrow a known good working carb from someone to test with?
Has anyone fooled with the advance curve or changed the springs or weights in the distributor? Does the vac advance unit have a leak? Does it hold a vacuum?
