The Stovebolt Site Forums The Shop Area Engine Shop Rebuilt Carb now Spark Plugs Keep Fouling

Jon G,

That is good advice. I really didn't realize that it could idle rich like that. Mike's Carburetor site said mentions that you can test the jet size by "operating the vehicle for 20 minutes at sustained speeds." Then I would pull the plugs and check for carbon fouling. I think I just read that wrong and thought I could idle it for a while and get it warmed up. My grandfather had run the truck for years and I doubt he ever changed out the jet size.

I have a friend in our church who is much smarter than I am when it comes to all this. He is going to come by with the tachometer, timing light, and vacuum gauge and help me check all that more precisely.

Thanks for your help!
