No fire at 2 & 3 acounts for the cold pipe. check the distbitor lobes and make sure the points are opening ( sparking ) 6 times. Then put a spark plug or glass tester directly into each of the dist. cap terminations one at time--this will let you know if the cap is good. Then check you wires--- I have purchased new ones that were bad right of the box.I do not think the low compression on those cylinders is low enough to cause a cold pipe. I think the problem is in the ignition. Paul
