A friend was telling me that he had to open the fuel adjusting valve several turns to get his car to run and that it would not idle. He thought there was a problem with the carburetor. He dropped off his carb for me to look at. I opened it up tonight and can not believe the amount of carbon buildup in it. It looks like the inside of a tailpipe. The idle, cap and main jets were all covered. After cleaning it up, I can find nothing else wrong with the carb. All the passages are now open and jets (original) are the correct size, float set right etc. What could cause this much carbon buildup?
