Hi guys,

Today my B & S wouldnt start, so i pulled the carb apart to clean it up.
Once i put it back on i noticed that regardless of the throttle position the white throttle butterfly clip will not move.

This is the first time i have cleaned the carb on this mower.

Is there another spring or something missing, hence why it wouldnt start in the first place OR have i put it back together wrong?

Thanks
Mark

The linkages look correct. If you can move the white thing aka throttle shaft back and forth without binding then you are fine.

Thanks,

Am i correct in saying that the white tab in the photo wouldnt move unless the mower is turned on / carb is under load?
The whole linkage moves freely.

The spring will hold the throttle open when the engine isn't running. But when it starts the rod coming from then other direction will pull against the spring to regulate the speed.

In the photo the throttle butterfly is fully open and against the throttle stop.
The governor pulls the other way and closes down the throttle so the default position is WFO
The spring pulls against the govenor and trys to hold he throttle open.'
Now in your photo it looks like the anchor point for the spring is bent back.
This oft happens when you run into a bush.
So if it won't run at sped, bend this tab back a little bit but be careful there is a fine line between too fast and BANG.
