Basic rules for tuning up points ign. cars.

Always set dwell 1st. 30 deg. for any v8 gm.

Always set timing 2nd. Make sure vac advance is unpluged.

Adjust carb last.

Reason for this: dwell makes a difference in timing, and carb tune up. timing only messes with carb tune up. Adjusting carb will not make any difference in dwell or timing.

You use the vac gauge just like you would the tac. look for the best vac reading when adjusting the carb.

Do it right and you get.....

The vacuum hose that is connected to the dist.does it go to a vacuum port in front of the carb?When I disconnected the vacuum advance to ajust the timing it died.I'm pretty sure that its no suppost to do that.

I would put a new set of plugs, a condensor, and a new set of points in it. I would check the cap and wires also. That way I would know for sure all the parts were good.

Where does the vacuum advance hose from the dist. go to on the carb end?Mine is connected to a port on the back or the carb right on the bottom.I think that is a constant vacuum any ideas?
