I have looked everywhere on google but none of the engines seem to match the throttle layout I have? I have replaced the govenor spring with a new one but that didnt help. The throttle control at the front of the mower moves, but this doesnt move the throttle control at the end of the govenor spring, should there be a second spring? I can manually move the second control and this alters the rev, so no valve issues (?), but not sure what is mean to move the control?
I've attached some photos so I hope that help? Many thanks and apologies if Im too vague... its an old machine so no silver plate with serial nos, etc.. and clearly no expert!.. thanks
