firing problem

Naw, I was talking to redneckjeff, he's supiciously silent now about his ignition (carb )problem. I gave it more thought and a backfire will also result from retarded igniton timing but I see that he said he tried adjusting that already. His so called not firing cylinders are caused by the lean condition. It's too easy to check the firing of each, all that's needed there is to check for spark. I think too many guys who are new to carbs think that somehow a carb pumps fuel into the engine like fuel injection, hence the mind thought that bigger is better when it comes to choosing carbs. And also the popular misconception that if one is too big or small, all that's needed it is to "jet it up" or "jet it down" to correct it. Maybe I did come off too strong in my first reply, but his statement that the carb was "more than enough, so it can't be lean", set me off on a tangent. It just showed me that he didn't understand that a carb problem and an ignition problem can make the same end results and can be confused with one another.

Maybe they are firing just at the wrong time. Any chance when changing out all these ignition parts that the wrong firing order for the cam was used?

Glad you got it fixed. I was gonna say the firing order was wrong. Went from a 302 to a 351 grind and forgot to reset the order and had the same problem. It'll run....just not in gear or long.
