Hi All,

My 53' 3600 with a 235 became roadworthy this week after lots of work. ( woo hoo! How fun is that?)

When driving it performs well except at around 1200 to say maybe 1400 rpm where it acts like its suddenly running on about 4 cylinders.

I put an electronic ignition in it, so no points or condenser to worry about. The distributer does move when I rev it ( It didn't just last week) Fuel filter ls new and clean.

So when driving all is peachy until I get to about 1300 rmps. Under 1200 or so it purrs / after about 1400 it really has some pep. ( surprisingly so)

I'm wondering if I should start with the vacuum advance? As always..thanks in advance for the help!
