Thanks Bill. I'll try again...
I have a '62 Chevy C10 with a 235 in it. I just can't seem to get it to run right. It runs rough during acceleration. Once I'm up to speed, it runs pretty good. It lacks power and I'm getting about 8 MPG. At idle, there is sometimes a popping in the exhaust, like a burnt valve, and the tach needle bounces by about 200-300 RPM at idle (no pattern to it).
Here's what I've tried/checked:
• Timing
• Cleaned spark plugs and set gap
• new plug wires
• new points and condenser and cap
• new distributor
• New valves and seats
• re-set valves
• re-set timing
• re-gapped plugs
• re-set points
• looked for bent pushrod
• re-set valves
• took the intake and exhaust manifold off and put new gaskets in
• switched Rochester carb for Carter carb
• Compression test 130-135 in all cylinders
Something I noticed today is that the exhaust gasket is blown on the second port between head and manifold (can’t tell if its cylinder 2 or 3, because it’s the same port). I can feel occasional puffs through the leak, but it’s not regular. It seems that when the puffs come through is when the engine misses a bit and the exhaust pops.
Anyone got any ideas???
Thanks!
Glen
