Make sure you check your squish (piston clearance with combustion chamber (squish band)) try 0.025” 

It’s a neo-tec, they build them to blow up! Most of them guys that buy them post on their group they blow up in the first 10 minutes, then spend a month fighting to get a replacement 😜😂

Nope, it didn’t blow the spark plug out, I did a decompression delete (plugged that hole) plug was ok, but the old cylinder and piston were sure scuffed up inside
