I have an engine bigger than 33cc. I believe it is a 77 or 78mm clutch. I have looked all over and I found for $10 at Daves a clutch housing. I also found the bell and shaft for another $15. My question is , is that the best out there, I have had trouble googling Clutch Housing or Clutch Drum. There are very limited info out there. Anyone knows who sell dem drums for a weed wacker style engine?
