Chainsaw Repair

Ok very nice and good work.

I have a few questions.   First the pink on the schematic is that for the Oscilloscope probes.
Second does the 1 microfarad capacitor have a faster discharge time over the 2.2  microfarad cap and hence affecting the timing.

You might want to coat all your components in epoxy to protect them from moisture and oil.   

Could you go to a larger working voltage on the capacitor to prevent it from getting to hot when making long cuts.

Also did you wind the pulser coil your self.   

How high in the RPM's will this circuit be good for.    Like say up to 14,000 or more.   

Some great info and is good to know you can always come up with an ignition for an old saw.
