The other day I mistakenly added to much oil to my gas. The blaster has fmf pipe. Oil injection delete. Open air box with uni filter, and the head mod. I drained the gas and put the 32:1.in with a brand new plug cause ethe other one was black .It basically sounds like an engine bouncing off tev limited when you pin it down low.is fine. Thank you for your help. Damn I learned my lesson
