140 Throttle

Postby Alex Hart » Mon Jan 20, 2020 7:50 pm

Hey y'all, I know this has probably already been discussed before but I can't find it. Anyway, The throttle on my 140 has in my opinion way too much play in it. The low idle on the engine has the handle by the steering wheel at about halfway. When I push the handle all the way to the front, it is largely unresponsive. Any ideas on what to do? Thanks.

There is a rod that connects the control lever to the governor. The front of that rod connects to a lever that is integral to a shaft that goes inside the governor housing. That shaft runs directly in the governor housing, no bushing. That is a heavy wear spot that reduces the stretch available to the governor spring. One fix is to drill that hole in the housing to accept a bushing. Or you may just have a weak governor spring.
