Here is my Weedeater 25cc conversion. G10 epoxy board intake, Drilled out WT-363(off a homelite 25cc), electronic enclosure box muffler, Carr Hub & mount, Weedwacker velocity stack, lightened flywheel, MA 16x6 prop (The engine has no trouble turning this prop, I need to try a bigger one).
The engine hand starts and runs great!
