Its fuel. I started it today and let it idle for a half an hour. I brought up the RPM's and held them high for a few minutes and after a while I started to see an air bubble in the clear fuel line. the bubble got bigger and was about a six inch long open area in the feul line and after a little time it drank the fuel in the bowl and started to flubber. so now I'll go after that pick up in the tank. I needed to get my fuel guage working any way. thanks for the good advise
