Well that's exactly what happend.
I got this cammando for nothing and was t starting. I fitted a new spark plug and off she went. I then went and cleaned it and while I was at it service the carb.... I also got anotehr pull starter off another p/t I had laying around with a very good o ring as the original one I had on it lost its tension which il need to fix.
Started it and was never the same. Actually revs high on idle on mid way low and run back to full crank... Scares me
