Glad 'yer make'n progress...double ck timing and vac advance.

After it's warmed up at idle, raise it just to the point of backfire, spray the blue w/washer stuff into the carb a little at a time.

After it's feeling better.....LOF asap.

I don't think riching up the carb will help, 454s will overheat or just stop way before a too lean will cause a backfire, in non-racing engines.
Most likely your gummed up valves or timing is still off.

454 Help

Cracked cap would be the first thing. If not that, check wires running to 5 & 7. If these wires do not cross at right angles, they will induction fire causing probs like you describe. Wires that follow each other in the firing order should NEVER run paralell or induction firing will result. Firing order on your engine is 18436572. 5 & 7 are on the same side of the engine (adjacent) so be sure they are in the outsides of the wire loom stringer and if they cross cross them at 90 degrees.

Great point. I had forgotten about that.

UPDATE! It,s Official, I now have a home that motors, WaaaaaaaaHoooooooooo. I enlisted the help of a throrough gear head friend of mine and he made a few adjustments, switched a few wires and set the time and she purrs like a kitten. I have taken it out and put it through some easy paces and she seems to enjoy the excercise. Thanks to all of you great Airstreamers.
