Thanks Norm,
I was thinking of the flywheel as the alloy part on the bottom just above the boss, with the magnets etc for the magneto. I guess the steel part inside the motor is a flywheel too but I would have called it the crankshaft. Just terms I suppose but now I understand what you mean. Have another look at it, I wonder if the bearing has a lot of play in it perhaps because of the very tight belt drive. It has to be very tight to avoid kick back. I think its too tight for long bearing life.
Your PT 24 pulley is now very similar to the way my substitute ended up. I think it started life as maybe an automotive alternator pulley, or perhaps air conditioner compressor pulley. Probably sourced by a visit to a car wrecker. After I turned it out to fit the standard PT boss, I filed a couple of grooves in it to take the PT boss prongs. Seems to work OK.
The belt that came with my FC 24 was an 11A1180 automotive fan belt. That means 11mm automotive They are very cheap like $12.00. . It was too long so I replaced it with a 11A1155. Its also a little long but the next one down is 11A 1130 but I think that would be hard to get on. I read on this forum that the Victa belt is 11M 1150 and probably is Kevlar or aramid reinforced, so much better but much more expensive. Time will tell how long these automotive belts last. So far so good is all I can say. The original one looked quite old but who knows how much work it actually did. They are all polyester so I think they must stretch more easily.
All the best
Jeff
