Got my fingers into one of the Rovan 45cc motors today, BOY they need help in moving some cooling air!!! .Sooooooo this is what I came up with.... I took the fan shroud and flywheel and pull starter off a Kingmotor 30.5 motor and also its flywheel nut, set aside. Removed the shroud, flywheel and easy start recoil and the funky standoff nut and starter engagement thingy from the 45cc and tossed that crap
in dumpster. . I next filed off the two small nubs on the 30.5s blower housing and then put the whole mess on the 45cc and it fit perfect and now the 45 is normal like the rest of us now and blows a crap load of cool air across the motor . I also reused the larger "T" pull handle from the 45 junk and replaced the pull cord with big cc chainsaw super cord. BINGO EZ
Almost forgot , I also used a metal starter engagement ring in 30.5 recoil before installing into the 45 retro fit
