Pulled apart at the moment confident it's not an air leak, timing @ 18 btdc might move to 17 btdc main jet 120 from 115 pilot 55 from 50 air mixture moved from 1.5 turns to 2. HTH |

instead of increasing the squish gap that can lead to detonation and pinking the combustion chamber should be reprofiled.
