[QUOTE="Trikky2, post: 483055, member: 240"] First check that the timing mark you are using is correct. Find/establish TDC by inserting a pencil down the spark plug hole. Once your sure the timing mark is right, you can check the timing with a strobe. With the vac hose off it should be at 7.5 BTDC at tickover and at around 3500 rpm it should go to about 28 BTDC. With the vac hose connected at 3500 rpm it will go to 32 to 34 BTDC. If it doesent advance with the hose off then the weights are sticking. If it doesent do the extra advance when the hose is connected then either the vac canister is faulty/leaking or the points base plate is seized and is not rotating when the vac canister is pulling on it.
