My 2000 Ficht 150 starts and run great at low speeds but I cant get any higher than 4000 rpms and it sounds like its pinging or detonating. The motor surges like its wants to go but never does. The plugs have been changed and the compression is good. I also drained the tank and put in fresh gas. Please help.

sounds like preignition to me.

could be lean caused by wrong air fuel ratio.
