Is it possible for a magneto to fire if the impulse isn't working. I'm wondering if it will fire if I tow the tractor to get some higher rpms than just using the starter although 12 volts spins that thing pretty fast. I can't get a spark on my new to me BN and I can't tell if the impulse is working. The tractor has some add ons so its tough to turn the engine by hand. I had no spark last fall and found out the condenser was bad. I had one that gave me spark then but now nothing. Points are clean. I've never heard this tractor run so I can't say what it was doing before I got it. These are the situations where I like having a hand crank but the add ons won't let me use one on this tractor.
