hey scotty, love the shows, I have a 91 GMC Sonoma 4.6 6 cylinder with a carburetor the truck is starting to shake while its idle. I have changed the spark plugs and cleaned out the carburetor and it still has got that shake. any ideas?

heck, that old, odds are the carb needs replacing. Me, I'd throw it away and bolt on a new edelbrock carb rather than mess with that old thing
