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 6 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.
Expert:  J.R. replied 6 years ago.
Check the drive belt. Your mower is the one that is controlled by the tension of the spring.
Customer: replied 6 years ago.
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.
