John Deere SX75 will not run ,, PLease help !!
I have a 1988 John Deere SX75 with a Kawasaki 9 hp engine ! It would not start it cranks fine , but had no spark ! I replaced the coil , the spark plug , both with no effect , then I replaced the igniter & it started and ran for 20 minutes , then quit , it would only run in neutral for some reason , (which I think that is what the actual problem is !! The ignition curcuit is always grounded ! I have tried removing the ignition switch and running jumper wires to power the mower and then crank it , but something is keeping the ignition wire grounded !!
I will appreciated any guidance or help any one has to offer ! I worked as a mechanic for 25 years , but this machine is kicking my tush !!
Thank you ,
