As you have dual exhaust have you done the dollar bill test?

Don I didn't use a dollar at the exhaust tips.  But did use s pieces of paper.   The drivers side is very consistent and sound mellow.  The pass side will poof (pop) the paper or your hand.  You can definitely tell a huge difference.  Doesn't suck the paper in though

Pour either down the carb, with engine running and warm, engine must be revving to abut 2000 rpm, pour in can slowly, then shut down, start it after a couple of hours, a lot of smoke will ensue, and maybe loosen that valve.

Do the compression test first and see where you are at. Hopefully you don't have a leaking head gasket at cyl 1...

When you say pour in can. Are you talking about the marvel mystery oil ?   If so how much ? Size of can that is.

Finally found my issue.     After lots of worries and frustrations.   The ground wire ( clothed wrap) wire.    Looked fine.     Was gonna make new anyway. Running outta things to look for.   So completely ( minus shaft ) disassembled the dizzy and cleaned and ran all new hardware.    Ended up being the ground wire on plate.  Wire inside of jacket was burnt or burning.  Had some black on ends.   Anyway. Repaired put back together.     Car is running as should.   Very smooth , k thought i was going crazy there for a bit.  Car has been down well over a month.  Over a simple small wire connection.  Just goes to show.   Don't over look anything.   I'm happy now though.  You bet ya.      I'm glad I didn't pull head.   Have 18 "s of vacum now timing is 6 degrees BTDC.

Congratulations! There is nothing like the feeling of satisfaction you get from making an old machine run properly.

The cloth wrapped ground wire that's screwed to vacum advance plates.

I kept reminding myself to ask you to check this, and had it on my mind, bad on me should have asked you about this right away.

Glad you found it, and this wire has been a problem for many others...

I had that same problem last year. I mentioned it on another thread but didn't think to mention it here. It is easy to overlook.

Thanks Fernando.  That's a great pic.   I don't have that in my manual.   But I'm not using that lower part anyways.  Mine has a block plate on it.   I'm running dual headers.
