<VV> Fwd: 110 PG with rough idle and wanting to stall at stops

[Stephen Upham]

I'll triple check that although I have been all over that area due to  
it possibly being a source of bad downshifting PG  (kicking when  
downshifting coming to a stop) - that is now greatly reduced though  
not completely eliminated.  Torquing the carb attaching nuts to 10-11  
lbs seemed to be the partial solution.  I even went to the extreme of  
putting hose clamps on the junctions of the rubber to metal on the  
crossover tube.  I'm also pretty sure that I didn't tighten them to  
the point of fatiguing the rubber, but I'll check them anyway and  
remove the tube and put the Mityvac to it to check for leaks.
As far as the Pertronix, electric fuel pump and distributor, you are  
right, they could be the cause of the problem, also. But the same can  
be said of the original equipment items.  I prefer the advantages of  
the system that I use, and therefore, will have to take the risk of  
them malfunctioning - which may or may not be the cause of the  
current situation.  What I really need is a step by step to begin to  
isolate the cause of the current situation.  You have provided that.   
I'll let you know what I find out.

Thanks, and hope all is well with you,

Stephen
