Hi !!
I have a question about vacuum advance.
I have read that the vacuum is highest at idle and when you open the carburetor throttle the,(wot), vacuum decrease.
I tested the vacuum advance on my distributor...at idle the vacuum works nice.,, (it engage) ,, ..but when i open the carbuteror throttle , (wot) , the vacuum stays on ...does not go back to initial.,(except when i stop the engine) .. ..ANY IDEAS ???
