Ok, this is the cause, don't ask me why. I JB welded up the 4 holes in the back of the decomp valve. No kickback but it immediately blew the plastic cap out of the valve, kept running, I pushed it back in and held it, this then blew the JB Weld off 2 of the holes I had covered over. With only 2 holes covered the motor will now start fine without any sign of it kicking back. I now have to find a way of covering 2 holes without it blowing off. Maybe cut a curved strip to go around and cover 2 holes and hopefully the JB Weld can hold it on
