Technical 41buick starter question

is ther a way to wire the starter to a regular key switch? just rewired to 12volt and cust wants it this way.as the old way is hold it to the floor to activate the switch on the carb.also , how is the witing done stock to make this work as there is two studs on the starter and if i hook it up i have to ground one to make the starter spin but wont disengage until i unhook the bat.i also have a 52 buick starter with one stud that i think would work.or i could change the solenoid on the stock starter.any help would be great.thanks

 

well i took the starter off the 52 buick junk car.tested good onthe bench.tossed it in the 41 anf works great.gonna get it rebuilt for reliability.

 

either should work. I took the carb switch wires off and ran them in the cab. installed a push ****on next to key switch. I also got rid of the factory starter relay and installed a mag solenoid.

 

First pic is the stock wiring, 2nd pic is what to change for a starter ****on instead of the gas pedal starter.
