Re: Exhaust "bypass" valve? Also..timing

["Gary H." <62to65mopar@xxxxxxxxxxx>]

The only way I remember to remove the exhaust bypass valve on the exhaust manifold is by taking the exhaust manifold off. Maybe you can figure out a way to use some wire to tie the valve so it is open and quiet all the time. 

Vacuum, stalling and rough idle. Maybe the Mopar has a small vacuum leak? 

Also check the rubber fuel line that goes from the gas tank pickup to the fuel line. If it looks old, replace it. 

Good point from Eric on the octane and the contemporary car's computer controlled tweaking; on our cars at times it feels like it is the human who must "adjust everything 1000's of times a minute to make them run wonderful." :D

Thanks,

Being that 10 is the only number on my timing stub I guess that's what that is. Now after putting it back together and taking it in the road...no difference.  Plus it had a rough idle. Now I noticed when I adjusted it to 10btdc with vacuum advance still on, it idled smoother...didn't have any noise, but taking off and in turns it almost dies...what should I do to get it right!? It doesn't have points, electronic ignition.
