| | | | Joined: Feb 2001 Posts: 81 Shop Shark | | Shop Shark Joined: Feb 2001 Posts: 81 | I have a 62 1/2 Chevy truck with a 235 ci engine. Problem is the carb floods if I have driven about 15 to 20 miles. It dies after I have stopped the engine and try to start and take off again. After dying once it runs fine. I have adjusted the float according to specs using the card that comes with the rebuild kit. Even changed the needle back to a steel one frome the rubber tipped one. New fuel filter made no difference. Any suggestions?? Thanks for any ideas.

Yes I do have the gasket/spacer under the carb. The heat riser valve is free also. My next step will be to wrap the gas line with insulation from the fuel pump to the carb. The gas line runs very close to the manifold on the drivers side of the engine as the truck has an add-- on ac system requiring rerouting of the gas line. The problem of flooding just began recently as I have been driving the truck for 30+ years. I did install a new coil but don't think it caused the problem.

Boy was that a problem when the sun came out. flooded carb every time. just a thought!....curt | | | | | Joined: Feb 2001 Posts: 81 Shop Shark | | Shop Shark Joined: Feb 2001 Posts: 81 | Thanks for your thoughts Curt. I have a locking gas cap from LMC on the truck now. Will try the old cap again. My next step is to decrease the gas level in the carb. Sometimes the "official level set by gauges is too high. When the sun comes out here in Texas it gets very hot-and that is already happening here. I may have to buy another carb but hate to spend $200 for a rebuilt one with the same problem!
