Small Engine Troubleshooting Problems? Ask a Mechanic Now.
Welcome to JUST ANSWER small engines, let me try to help you !! I don't know it all, but maybe together we can get you a satisfactory answer!
Do you have a voltmeter to check the battery voltage when trying to start? Is the charging system keeping battery voltage up?
OK< so what is voltage at the switch wire on the starter solenoid? It may not have enough amperage to close the solenoid. Try a wire direct from the keyswitch, to the tarter solenid, mirroring the existing wire.
I see question is till open, did new wire make difference? Please rate to close and get me credit! Thanks!
