Hi all! I just got a 1970 CT1 175cc. It's my first bike, and the first bike I've ever worked on, so I'm feeling a bit in over my head. Anyway, I need a new carburetor and I'm having trouble finding a stock carb. Could I get a carburetor from any other 175cc yamaha 2-stroke and use that? Would a new mikuni round slide work? I'm not sure what size to get. I don't know if this matters but the engine is on 5th overbore. Thanks! I doubt this will be my last posting looking for help with this bike
