  • / How to check the kill or shorting switch on a D600
I am trying to get a IH model 3311 from about 1973 to run. It has Lawn Boy D600 engine.
Everything looks good. Coil checks out, spark plug is sparking, it is getting gas. Cleaned carb, kill switch is connected, took flywheel off and governor system looks in order.
I am going to take the blade and muffler off to check the exhaust ports and to check the lower crank seal.
I wasn't sure if the mower would run if the kill switch was bad, even though it showed it was sparking when pulling the starter rope.
My first Lawn Boy was a model 7265 from about 1976 with a D601 engine but it had a plastic modular carb. It quit running after about 20 years. I got a new coil and it still wouldn't run. So I took it to a mower
shop and they found out that the kill switch was bad. Does anyone know how test to see if the kill switch is faulty or not? I am not an electrical wizz.

Switch was bad. Swapped it out with another switch from a running mower and it took right off. A new kill switch is on its way.
It helps to have extra mowers setting around.
