25 HP V-Twin Runs at Excessive Idle and Will Not Throttle Down
I have a Briggs and Stratton 25 HP Model #446777-0165-E1. It starts with no problem, but it runs at a excessive high idle and will not throttle down. I have replaced the plugs, carburetor, and governor gear. I have adjusted the valve lash, governor, throttle and choke cables. I am stumped. Any help will be greatly appreciated.
