Vacuum advance on 318

I think something is way off in my distributor.

My advance hose has been disconnected since I bought it. It's a transplant engine, from /6 to 318 (came out of a truck)

First off, this is an electronic ignition correct?:




I set the ignition timing to 10*BTDC today, attach vac advance (to port above butterfly) engine stalls.

Leave vac advance hose disconnected for now. Plugs are still fouling out, the carb is good and not running rich but my MPG is terrible.

I want to get the vac advance working properly, this is a street car and I could benefit from the extra MPG etc. It may have a sporty exhaust and I'm putting in a mild cam and a 4bbl but the stock ignition or close to it should be fine for what I need it for. Definatly not a high RPM motor.

I think the vac advance diaphram is fried or overly sensetive, it wasn't disconnect for nothin' I suppose. What else could give simliar symptoms?


TIA
