My 1988 Toyota Truck 2WD 2BBL Carburetor has rough starting problem.
If it has been sitting for over 8 hours it blows black soot after start up out of the exhaust for the first few seconds after I press on the gas peddle.
Then it idles rough for about the first 20 minutes whenever I am at a stop light. It seems to have a wave sound like it wants to stall. Sometimes after I get to my destination it still runs about 2 or 5 seconds after I turn it off. The odd part is sometimes after I run the truck for 20 minutes and turn off the engine and restart it runs great.
Please advise how I can fix this problem?
