RE: Toro 25 prop hub
I have taken a flywheel off a homelite & mounted it on my drill press. Then I took a holesaw (1 1/4 in. Dia) & cut the center out for my magnet for electric ignition. That way you can use a hub purchased elseware. I use carr engineering or wackerengines for my parts. I have lightened a home 1 1/4 lbs.
