Truck won't idle
I must admit I have not driven my 62 GMC with the Holley 500 cfm carburetor that much in the past year. The last time is ran normal was my trip to the dump in mid September. When my cousin and I had an errand to run last month it just did not want to run at low speed at all. It flat refused to idle at all, dying at every stop light or when the speed got too low or throttle position got too low. I figure my idle circuit may be blocked with crud from that oxygenated fuel, but the last time I filled it's tank was with pure gas no ethanol. Any ideas??
