You also want to check the polarity so the front (weaker) cylinder gets a little more help….. and it is definitely the front that gets the weaker spark. When retarded, it is way past the flip point …. flux reversal …or whatever you want to call it.
This is a different mag body than the KVF, but there are manual advance end housings out there that will bolt onto the KVF. The slack wire advance ones are very rare… at least over here they are.
This is the setup I used to cut the slots for the manual adv/ret linkage. The stone in the foreground was reshaped with a diamond dresser so it would create the correct V shaped notch for the adv/ret link.
