The flywheels on both my Homelite 25 and the one on my 30 are both Walbros. But the one on the 30 came from a chain saw. The one on my Ryobi is a phelon and it was a long ways out of balance originally.

Back a few years ago, the last time I looked in the Homelite catalog, there was no mention of what brand either the module or the flywheel was. The dealer assured me that you may see either brand on the weed whackers or the saws. The brand for each flywheel brand was marked on the back side.

I looked at the Walbro catalog too and found the ignition modules but no flywheels. Maybe the Walbro flywheels are O.E.M. propietary?

Ralph, I can send you a long shaft one if you want to see the brand?

Enjoy,

Jim
