Default Lawn Mower Idle Oscillates


Yup, could definitely be a spring. I read a little book on
repairing small engines from the library recently, and it
also suggested it could be any spring or linkage which
connects the governor system with the throttle.

You may have to remove the engine cover to fix this one, but
the good news is that if it's packed with grass or other
debris, cleaning it may resolve the issue for you (anything
that binds or blocks the spring(s) or linkages from proper
operation).

Good luck,

My Murray lawn mower idle oscillates up and down, I can see the spring
on the carb moving about 1.5".

I there a spring kit or some kind of throttle control that may fix
this this?

I rarely use this lawn mower and am about to put it up for sale, just
thought I'd fix this problem before advertsiing.

Its a Murray riding lawnmower, model 30552x12a w/a Tecumseh 10 HP

Thanks for any input..
