This was a pull start engine to begin with and I just installed a pull start delete so yes the back plate was off. There arent any visible scoring on the back plate to indicate the crank/conrod was touching. Turned the engine over with the back plate off and was still tight at TDC. Crank wasnt touching any other part of the engine either and spins smoothly

The crank spins freely and piston slides up and down smoothly. The clip is still firmly in its place and have not made contact with the sleeve.
