I've got a 1970 521 with dual points.
After a recent breakdown on the freeway, i got the truck running again with new points, condensers, cap, rotor, and wires. After the tune-up it had a rough idle and was sluggish at low rpm. If I could get it to a high enough rpm it started to run better. Today I took the vacuum advance off, and it immediately began to drip fuel. I was able to squirt most of the fuel out by pushing on the plunger.
While I wait for the rest of the fuel to evaporate, I thought I would post and ask for your thoughts on this. Will gas in the vacuum line cause the problems I described? Will gas ruin the diaphragm in the vacuum advance?
Thanks
