Hi Chris, welcome here.
Great mower you have there, the Victa 2 strokes were the best mowers ever made. Downside with your one is catchers are hard to come across and not broken.
I just drill the 3 holes and tap them 1/4 whitworth . Probably a better option is to forget about removing the fanwheel and just fit an ignition module into the wire that goes to the kill switch wire that goes to the carby. This means the points and condenser are not needed and can be just left in there
