I bought this tractor and had spark, but no juice to the starter. Replaced solenoid, now that works but I have no spark until I turn the key to the off position. I replaced the key switch, and when I did that I had spark and like your supposed to I had to push in the clutch. Went to try and start it after supper and now I'am back to no spark until I turn the key to the off position!!!???? What the hell is going on? any info will be greatly appreciated.
Dave

I took the points cover off and with the key on I push the points apart and get no spark, but if the screwdriver is touching the points it will spark.?

Then the points are dirty and need to be filed or replaced.

If you remove the spark plug and lay it on the head with the spark plug wire connected, you should get the spark plug to fire every time you open and close the points quickly with a screwdriver If it won,t fire then the coil or condenser may be bad or the point gap is way off and not opening.

You should not have spark with the key switch in the off position. You may have the wrong solenoid or the wrong key switch. Compare part numbers with the old ones. You may also have a bad new key switch. It happens.

The only time the spark plug when laid on the head will fire is if my screwdriver touches the points hen I push them apart, or when I turn the key to the off position.

When I put the new key switch in everything worked perfectly fine once. Now I'm back to square one.

Dave, use a voltmeter set to DC and connect the black lead to the ground terminal on the battery and the red lead to the (-) terminal on the coil. Remove the spark plug, turn the key to RUN and turn the engine over by hand two or three revolutions. The meter should alternate between +12v and zero volts as the points open and close.

If you have steady +12v the points are not making contact or the wire to them is broken. If you have steady 0v then the points are staying closed, are shorted, or the wire to them is shorted.

By the way, verify that the wires on the coil are attached correctly; ignition lead from the switch on the (+) terminal, wires to the points and condenser on the (-) terminal. You should have +12v at the (+) terminal with the switch in RUN and START positions.

The correct point gap is .020 thous, the correct gap also has a lot to do with the way the engine preforms. Less than .020 the engine is retarded and sluggish, over 020 the engine is advanced to far and will ping under load.
