1990 140 johnson stops running?

[vip-vindicator]

hello, just got this never messed with o/bs before.140 jhonson runs bad and will shut off after about 5 - 10 sec. unless you unplug engine harness then it instant runs fine. vro is unpluged and capped off. yes im mixing 50:1. i went to the ignition switch pulled of the ground wire running to the motor to kill it. black with yellow strip and it runs good but of course will not shut off by the key then. what i would like to know is what can send a signal to kill the motor. temp switch? motor is not hot but i guess bad switch could do it or does it just run the buzzer. or just a bad ignition switch. its on a 1990 sunbird.


Thanks

replace ignition switch. besure to get the correct switch, or you can blow all the electrics.
