Throttle Control bracket?

Can anyone tell me what part this is? I need a new spring for the lever arm. There never seems to be any tension on the spring when I use the throttle control up near the handles. It's from a ST824 (model 924050)

You'll need the engine model number to try and get the right part. That screw adjusts tension on the spring for maximum rpm. You could screw it in to see if that helps or get a (very) similar spring at the hardware store and adjust it out with the screw.

That spring looks okay to me! I suspect the problem lies elsewhere... like the throttle cable may not be adjusted properly.

If you do want to replace that spring/assembly you'll need the full model & serial numbers off the engine. The model number should start with "HMSK80" or "HM80". This video shows where the info is located:

~1994 Ariens 924084 (ST1032) "papa bear": restored, re-engined, real nice!
1991 Ariens 924050 (ST824) "mama bear"
Toro PowerCurve 1800 "baby bear"

Be alert! America needs more lerts.

I think you might need to have that installed on the engine with the card linkage attached before you can adjust things. The governor spring will get much tighter tension when the throttle is set to high speed, and little tension when the throttle is set to idle, which is wher adjusting the idle speed screw comes into play

Check on YouTube for the right process to adjust the governor on your engine.

Work fascinates me.

spring

Thanks. The problem I'm having is that the engine revs at the same speed whether the throttle lever is in the high position or the middle position. It does rev down when I drop the lever into the low position. The arm that the governor linkage is attached to doesn't seem to move much.

Governor assembly inside the engine is most likely the culprit. It's a plastic gear inside the side cover that can break. You'll have to split the case to investigate. Did I mention I hate Plastic Parts?
