Chuddy, What have you got the points set on?
Your questions about the plugs.....my manual shows the firing order to be #1, 5, 3, 6, 2, 4; however, I can't find a photo either. Sorry.
Have you checked for a vapor lock in the gas line?
Also, when or have you had the gas tank cleaned & coated last?
I'm restoring a 55 Chevy 235 3100 1st series myself.
