That is not the whole fix,you need to find the brass needle valve incarnation body(whichhas a cap on it),remove and cleaned with small wire.put back in and you should be good to go. This controls the air mix and is non adjustable.

Hi, You have gum or old gas in the main jet on the carb, turn your fuel off, stand the snowblower on the front blower housing with handles in the air, remove main jet from the bottom of the carb and clean. Jim

John Deere L111 from 2004 surges in idle. Have replaced plugs, fuel/oil filters, fuel pump. Still does it.

Cleaning the carburetor is a good starting point. There is two versions the Briggs that were used on this mower. One had a single barrel and the other had a two barrel version. Both were Nikki carburetor that main jets that are held in place by tiny o-ring that shrink causing the jets to leak extra fuel causing surging.

John Deere 430, Sundstrand series 15-U hydrostatic transmission. The tractor, at low ground speed, surges as it moves, in both forward and reverse, at any engine speed. At full ground speed, the surging...

you sure your engine isn't surging... you would see it at lower speeds... my motorcycle surges at a certain rpm due to fuel ratio's at the one speed ( running lean )... so what i am saying is, could it be that the engine surge only shows itself at a certain ground speed.

or is it because of a hydro system pressure relief valve ???

I have a John Deere Hydro 175. It will run for 10mins then starts surging and dies. It appears to be overheating. What would cause this?

during the winter a mouse nest might have formed under the tin cover that would stop air flow to the cooling fins
