You can get the newer style bendix or you can do a tune up on the tractor.

It works like this......the bendix engages the ring gear on the flywheel & turns the engine over. When the engine speed exceeds the design speed of the bendix (because the engine is running) it disengages. (and I can never remember what RPM that is) All the new style bendix does is allow a higher engine speed before it disengages.

What is happening in your engine is that 1 or 2 plugs fire, the engine momentarily exceeds the bendix disengage RPM.....and it disengages before you have all 4 firing.

If you want to tune it up, just ask; plenty of folks can walk you through that.

And, if you want to pull the starter & replace the bendix, just ask about that as well. See tip # 36.

I have a pertronix unit in my 9N so if its a tune up issue .....it must be the plugs..........I just went through the carb

There is more to it than that.

Timing?

Cap, wires & rotor?
