I got the 25cc Homelite all cleaned up as I posted in another thread and used the 600 wet /dry with the acetone. and got almost all the glazing out,but as you said don't worry about getting it all.I think I'll make this engine into an airplane conversion as I already have three water cooled Homelite boat engines.On another Homelite I converted I got a lightened and balanced flywheel off Ebay,but can't find one yet,so maybe it's time to try an electronic ignition and go with a Bowman ring as suggested.The mount and prop hub will probably come from Carr Precission unless you guys know somewhere else that has good prices,since Wacker Engines is no more.
I also have a 30cc Homelite,a 28cc McCulloch,a 28 Husquvarna Mondo and a bunch of 18cc to 25cc Weedeater brand trimmers.Some will be fixed as trimmers,but some will be given a new job on the front of an r/c airplane.
