i have a 1960 solex carby on my vehicle and i rebuilt it coz it was not assembled when i bought the vehicle and i didnt have a fuel mixture screw so i went to dads box of series one carbys (solex) and pinched a mixture screw.

now in theory i should be able to stall the vehicle by screwing the screw all the way in... but it doest.

my thinkings are either there is a specific 1960's screw for the carby not the same as the series one ones, or there is air getting in through the vacuum advance for the distributer of similar so the vehicle still gets air and doesnt stall.

and suggestions?

The mixture screw being right in will only stop the engine if the throttle is completely closed.

Correct procedure is to start the engine, run until hot. set the idling rather high with the mixture screw right in, then unscrew it until the engine starts to hunt. Screw in again until the hunting just stops. Decrease the idle to close to 500rpm, and repeat, starting by screwing in until the engine slows, then out until it starts to hunt. Repeat these steps until the engine is idling smoothly at 500rpm. Never try and set idling unless the engine is right up to norrmal temperature.

If you have just assembled the carburetter, did you get the accelerator pump link correctly adjusted? There should be 0.020" slack with the idling screw backed right off.

Float level

Carburetter incorrectly assembled or diaphragm damaged during assembly

Accelerator pump linkage not correctly adjusted.

If there is the possibility of the mixture screw being too short, have you tried putting it in temporarily without the spring - this would allow it to screw in further if it is not bottoming.

Can't think of anything else -
