How can I adjust the engine speed on my Toro personal pace

Customer Question

How can I adjust the engine speed on my Toro personal pace mower?
I was cutting my grass when the speed dropped to a crawl speed.
It's 10 yrs old
Model # XXXXX
Make SR-21S
I located the idler lever and can get more speed when I pull on
the spring but it bounces back to crawl.

How old is the mower?
Customer: replied 7 years ago.
Model Number 20043
Name SR-21S
I am pretty sure By my records, I bought it in 2000.
I took the plastic cover off the top and found the control that picks up the speed. I can pull on the spring and it speeds up. Too fast if i keep pulling. But when I restart, it goes back to crawl mode.
I'm not good at the proper terms but if you have any more questions, let me know.

I went through that manual you sent me and I could not find anything for setting the run speed for a Toro personal Pace mower.

Check the drive belt. Your mower is the one that is controlled by the tension of the spring.

The drive belt isn't the problem. That works fine.
My problem is when I start the mower up it runs at about 1 RPM.
It is a Toro Personal Pace made in 2000 I think.

I thought you were talking about the self propel feature. You may have a bad governor spring. Here is what the spring setup should look like.

No pictures look like mine. I wish I could send you a picture of what mine is. Oh well I'm taking it in tomorrow because my lawn is getting long.
I do hope you get paid because I did accept and left you a $5.00 tip.
