Carburetor linkage diagram for toro 20588 - Toro Power Lawn Mower

This is the site I use frequently. There is a blowup diagram of the linkage. http://www.partstree.com/parts/?lc=Toro+Consumer&mn=22035

If I cross reference the engine correctly it is a TEC HSK 850 so the follow service manual should be what you need.

That sucks. I know. I'm guessing you have the standard Tecumseh set up that's on all the Toro's I work on (sideways carb setup). I've learned the hard way to take photos; I'll post the one I took. I apologize for the quality; the next one I do, I'll take a high res one but hope this helps ya out. I mean Toro Push Mowers. James

Go to toro.com web site. all the manuals are online.

Three options:

1. The carburetor throttle plate (closest to the engine is stuck); clean it with gumout and work it back and forth

2. the linkage is hooked in the wrong hole ; check the wear pattern on the throttle shaft plate to see if it is in the wrong hole.

3. The govenor arm or gear is not adjusted properly; loosten the govenor arm, push the throttle plate of the carburetor all the way closed. push the govenor arm the same direction all the way until it bottoms out. tighten the arm clamp. Test again

I recommend getting a manual or at least a free parts diagram from a local shop like www.arcolawn.com

Good luck

please vote me up if the fix was good.

PartsTreeRepairClinic may have a video

Remove the rewind housing and engine cover, clean the cooling fins and that should fix it.

If you have the pieces of the old plug, take them to a hardware store. Use the thread to find the one you need in their inventory. There are a number of thread designs that you have not mentioned, you can find it there. Good luck...Lee
