When i first bought it the guy told me it had to be jetted but it turned out the piston was blown because i put the new one in and it runs and idles just fine
i dont think i could of done it without this site and kens videos. the only thing i feel bad about , i started without any exhaust just to see if i put everything on right and it started on the second kick and my daughter (5) she ran like a bat out of hell
it was pretty loud
oh and i went to the last piston size 73mm it runs really good now
