OK... So I have rebuilt the carb and put a on completely new top end. Cylinders and pistons and rings. I went with the .050 bore and have got it all back together. I took it out today and tried to test the unit and I am still having the same problem I had before I replaced the top-end. It has no power and it seems to be starving for fuel. Should I have changed out the main jets to larger jet since I went to a oversize piston? Please and advise that might help me identify the problem would be greatly appreciated.
