Engine wont shut off
When I turn off the ignition the motor still runs till I put in gear and release clutch. Then after that it runs really bad till it drives for about 5 miles than it seams ok till you shut it off and stall the moter to stop it.
When the engine is running like crap the tack goes crazy????

Sounds like it's "dieseling", if that's a word.
I'd check the timing. I'd check for fouled spark plugs.
That being said, I'd first check the throttle linkage/carb to make sure the butterflies are closing completely. chuck

I know you probably don't want to hear this, but sounds like you still have distributor problems, the diesling is a timimg problem...do yourself a favor and drop a stock distributor in that car and all your problems will go away...

I'll have to agree!! You have a run on problem. We used to do this with demo derby cars by over advancing the timing to keep them running after the radiators would blow from overheating. We had to have a ball valve in the cab to shut off the fuel supply to get the engine to stop running after the ignition was turned off.

Sounds like two issues...(ignition maybe).... and carb setting or sticking throttle plates/high idle....
Take some carb cleaner and spray(cold engine) on carb linkage and clean...but you have posted issues with distrbuter recently..are you sure that is fixed..???

The funny thing is when the engine is missing the tack flutters and after going down the highway for around 5 miles it settles down and runs OK?
I may set the timing back a little to see if that helps. But the fluttering tack has me wondering WTF???

With an AC car, you should have an idle solenoid near the carb lever. With the AC ON, a plunger extends from that solenoid, bumping up the idle/engine speed to compensate for the AC.
With the AC OFF, that plunger should retract. If it's not retracted, that might account for the throttle not closing all the way, causing your dieseling problem. Chuck

Chuck may also have a point about the A/C...
