I need it! And it's even close to me!

I could do my own emissions testing too, huh? C'mon! Everyone chip in and you can come by and get analyzed whenever you'd like!

You can't go wrong! For these older cars, those machines are excellent for diagnostic work. Once you learn how to read the sine wave, you can quickly tell if a problem is due to an ignition propblem or other mechanical problem.

Obviously running too rich will cause plugs to foul, and it will begin to miss.

Another possibility is that your fuel filter is clogged. If you are only having troubles under hard acceleration, you could be starving your carb for fuel.

For rich conditions, don't forget to look at your choke, expecially since it is colder outside now.

I recently had a similar problem, #8 plug had come loose. This has happened a few times now.

I replaced the plugs and threw in a new set of custom-cut Accel wires, and the problem's gone!

I don't see the logic in it...but it works, so good enough for me.

Thanks all!

As engine RPM increases, the pressures inside the cylinders increase. The pressure of the fuel/air mixture can build to the point that there is enough resistance to snuff out the spark across the gap of the spark plug if there are any weak components in the ignition system.

Ahh, cool.

I was inspecting the old wires today, and a few had cracks right along where they sat close to the exhaust manifolds.

They weren't that old...perhaps 3 years. They were Accel 8mm's. Guess I'll have a more rigorous replacement schedule!
