well, that's unburnt fuel. Check valve adjustments and make sure the choke fully opens when warm. Also make sure timing/points/cap/condensor are within spec. It would also be a good thing to check the plugs. If their covered in soot, the engine has been running too rich.
Sans that, you could have a burnt or cracked exhaust valve but I'm thinking it's one of these items above.

I doubt carb icing then. Check the choke mechanism to make sure it is fully opened when warm. Also, backfiring was
it through the carb or exhaust? Check the valve adjustment and intake for vacuum leaks using carb spray at each junction while the engine is running. If the engine speed changes then you have a leak.

You need to make sure a) your oil breather is hooked up to the air cleaner properly, and B) your preheater pipes are hooked up to the muffler and not clogged with carbon.
Yes, this would cause the symptoms you have.

Tech question on the way home from t@p I had very litte power even with a head wind and seemed to up hill all the way, we stoped about 100 miles in to the trip and i checked the oil and noticed that the intake was very cold with sweat . What does the cold intake mean also it would backfire when I would run up the rpm and let off to shift34 pic carb?
Second question just rebuilt the motor in my bug the exust stinks and also has a cold intake with a 2 barrel weber.
