Gentlemen and ladies,
I'm looking for some help with a miss that I have in my engine. My truck is a 1966 Chevy C-10. It has a 250 6 cylinder motor in it. I replaced the carburetor with a remanufactured carb after months of trying to adapt a Holley/Weber progressive 2 barrel to it.
When I got it all back together it now has a miss. The miss is most pronounced at cruising speed. On acceleration it is still there but not as noticible. It causes the truck to feel like it is lurching when you are trying to maintain a speed.
Last night I checked the compression ratio on all of the cylinders and the were all in the 170-175 range. I put new plugs and plug wires in it. (I converted it to electronic ignition with a Petronix ignitor a while back. That is why I did not do points and condensor.) Tonight I'm planning to play with the timing, adjust the carburetor, and check for vaccuum leaks.
Any other ideas or thoughts?
Thanks,
Mike K.
