The original thread is do I have too carb?

The other day plugs were so bad car would not even fire got out only three of the header tubes were hot which happened to be all on the drivers side where i had changed the gap from .022 to .040.

So I changed out plugs from an ngk fr7 to fr5s and gapped them for .045 car started but still carb backfires etc... I powerbroke the car to put it under a load and try to clean out the cylinders it seemed to help. Did I do the right thing? the other thing is I am trying to get an email as far as the stats of the carb and stuff that the guy worked on but all i know now is he said it has a 6.5 powervalve and jets and etc... i dont know he said he had it written down somewhere.

If someone has an intake or carb for trade I am interested this race demon i think is just too much carb with the weiand team g intake on the car as well.

taco, are you getting black, sooty, deposits or burned, oily type deposits on your plugs?

I remember reading your other thread about a week ago, and you got some very good trouble shooting information. If none of that info helped, you may have something completely different going on rather than the carb, so don't get totally fixated on that area alone. Quite often we go to the carb first simply because it sits right out in the open on top of the engine, and it's the first thing that catches our eye and our attention. Check for vacuum leaks, oil fouling of the plugs, incorrectly connected spark plug wires, etc. before actually fixating on the carb as the only source of your problems. Good luck.

.045" plug gap sounds a bit extreme to me. if your ignition isn't top of the line it won't fire the plugs and will eat up some types of plugs wires. try .032" gap. while it's idling pull off the plug wires one at a time and see if the motor stumbles, if it does either the wire or plug is tits up.
