[DeTomaso] Exhaust popping

[Larry Stock]

Typically that is sign of a lean idle condition, give your idle screws a 1/4 to a half turn to richen the idle mixture. If your running a double pumper Holly, you have 4 idle adjustment screws, if you are running vacuum operated secondaries, there are just the two idle screws on the primaries.

       When I back off of the accelerator,  the exhaust makes a popping noise.
       It isn't  a backfire in the carb. Wonder if the noise is caused by way
       too rich setting resulting in fuel detonating in the exhaust pipes. Car
       is running uneven and I can smell gas inside the car. Do I need a carb
       rebuild or ??? Please email me. Thanks in advance.  Fred
