I just got done doing maintenance including new gaskets cleaning the carb and new air filter. When I put every thing back together and then I start it, it raving very high at full throttle coming off of coke and really low throttle at low throttle. I think something is up with my linkage but I don't see whats wrong. I can not find anything on this mower like manuals or anything to help me with this, so I am hoping you guys can help.
