I know what your saying. But it has 105 pounds in that cylinder; has spark on both cylinders, and has fuel. Has everything it take to run. But the right side don't run. The only thing I can think of is the the crank on the right side has moved off of timing. Im not just shooting from the hip. I tryed everything I could before I tore it down like this. Read a forum that said piston could be cracked or washed out the rings. But it all looks good. I have built a lot of different motors and have never seen anything like this before.
