Geez that dog carries a big stick.........
Have you ever pulled the distributor and the #1 spark plug and found tdc? There is a good write up on here somewhere.

Yeah he does. Here's the "stick" when he pulled it out of the woods last weekend. He's whittled it down a bit

And no, never done that. Think you mean dist cap, but I am pretty sure timing is there now. Wonder If maybe its crappy gas? Hell, could be a hundred things I guess.

You asked about the coil they could become weak over time and show up as a miss. If you still have a stock coil what are your plugs gaped setting. If I remember right they should be at .025

I do still have the original coil, and new plugs gapped at .035.

Coil's like $30 or so. Gonna see about picking one up. The coil and distributor are the only old links in the chain.

No i mean actually pulling the distributor to ensure your at top dead center and that your distributor is installed correctly. Post #9 of the below thread is what prompted me to do this.

On his he does not really need to do with this has long as the timing order is correct for the engine, number one plug wire is where the rotor is pointing for when the number 1 cylinder close to tdc on the compression stroke. He has a non fuel injection engine. What you link refers to is for a fuel injection engine. Which has a lot more to do with the firing the spark plug and fuel injection system.

Finding tdc on my carb'd engine seemed to smooth things out tremendously but maybe it was just a fluke

Swapped out the coil today, no change in idle.

There's a guy, Jim Varney, north of where I live who is a race car, hot rod engine specialist, who comes recommended from a neighbor. Called him, explained everything, and he doesn't know what's wrong with it, but is willing to tune the carb and engine, dyno it and set it as best he can for $85. At this point I'm thinking it's the path of least resistance.

I HATE to throw in the towel on this, but can't think of anything else to do.

Try one last thing first gap your plug to .025 see what happens.

A tighter gap is easier for the spark to jump. Lower resistance at the plug, meaning it doesn't need as much volts from the coil.

I'm game to try this. I have a set of Champion platinums that I'll regap to .025 and try it out.

I'll let you know

Its well-known that most engines will respond better to a "hotter" spark, which allows for a wider plug gap. If this 025 gap works for you, then it tells me that you could use a hotter aftermarket coil. Accel "supercoil" and MSD "blaster" coil are pretty well-known and established, they usually go for about $50.

I used to run an 065 gap with the HEI, and believe me it made a huge difference. But the stock replacement jeep coil just doesn't have the volts to shove a plug gap that wide. At least, not on a reliable smooth basis.

Replaced my regular copper top Champions gapped at .035 with regular copper top Champions gapped at .025, and she looked at me and screamed "HELL NO!". She didn't like that at all. Ran so much rougher, both at idle and with the throttle opened up.

I'm at a loss here. The upside is I know every screw, bolt, nut, vacuum line and wire associated with the carb and ignition. If only one was marked "fix me".
