Compression in the the 125 area. As for the carb after I rebuilt it it improved the fuel dripping from the one jet but not the other. Read some blog and found my fast idle screw too high rpms. So readjusted lower and then I could adjust idle screws then it ran great. But once the fast idle is adjusted too high it drips fuel again and runs like crap. So low rpms proper idle,runs great but not great enough to Change into gear and stay running. So really doesn't run great if u get me.
