Ky service manual This may help. I would start by taking the gasoline solenoid off the carb at the bottom and clean it out. When you take it out there is a spring and pin in it . While you have it out apply 12 volts to it to make sure the pin pulls in that's what lets gasoline in the carb. I don't believe the spec k had a low oil pressure switch but check the parts manual on which spec had one. Good luck the others will be along shortly to help. Ps if you have a multimeter make sure you have 12.7 volts to your start solenoid and with start switch pushed you have 12.7 v coming out of start solenoid. No light on start switch sounds like low battery or bad connection at start solenoid.
