King motor 29cc loss compression after tuning.
Hi. Today when i ride baja something shot and engine loss compression. I thought it was pullstart but it's not it. Pullstart run slightly and when the piston moves to the top it sounds metallic and run hard. What's happened? Recently i changed oryginal carb to walbro 668, pipe to ddm dominator and NGK Iridium spark plug. Power strongly increased, did engine could not stand this power?
