I found another option instead replacing the points and condenser or using a Nova/Megafire module on a Power Mac 6 and I'm assuming the older Mini macs too.
Picked up this saw at a flea market last weekend and did my normal routine for a saw with points ignition and no spark. Popped the flywheel off and used some fine sandpaper to clean the points which usually works but not this time. I then wired up a Nova module and got spark but the saw would not fire up accept for two faint pops. So I was thinking maybe the timing was off because of the flywheel design wasn't compatible with the module but I don't know for sure.
I've had good luck with these modules on other old saws so the problem was bugging me enough that It almost kept me from falling asleep later that night. I was thinking about a newer mini mac I had laying around and I figured I could swap the flywheel and coil over and just upgrade the whole ignition. Next day I got the parts off the mini mac and noticed the flywheel wasn't going to work because the crank shafts have a different diameter but the flywheels looked exactly the same. I know from other discussions about upgrading a saw from points to an oem electronic ignition that the flywheel and coil both have to be replaced to work but I took a chance with just the coil.
Long story short, the saw starts and runs great with just swapping in the newer coil. The only real issue and not a big one is coil laminates behind the slotted screw hole does have to be ground down so the side cover will clear it. The kill switch wire will have to be modified but that's an easy fix too.
The first pic shows the newer coil installed and the old one sitting next to it. Second pic is were I had to grind down the coil laminates. .
Has anyone else just just swapped a points ignition coil with a newer electronic one with success?
