[DeTomaso] (detomaso) engine stalls on start up

Sounds like you picked up some debris from the gas tank that has plugged the idle circuit in the carb.

You can try removing the idle mixture screws out from each side of the carb and spraying carb cleaner in the holes. Three things; first count how many turns it takes to turn the idle mixture screws in until they stop, then write that down as you want to put the screws back in the same amount of turns. Two, there is a tiny gasket that looks like a bushing that goes around the screw. It usually looks like it is made of cork. It may or may not come out with the screw. If it does come out,put it back into the hole before you put the screws back in. If the the bushing does not come out be sure it does not fly away when you spray the carb cleaner in the hole, or if it does find it or get replacements. Three, wear eye protection so you do not get blasted by any carb spray that bounces back at you.

This may only temporarily fix your problem as it will move the debris out of the idle passages but it will still be in the carb most likely. If that is the case you will need to rebuild/ clean the carb.

Hope this helps, it sounds harder than it is.

Ps, get a fuel filter!
