I have a Toro mower with the Honda GCV160LAO S3B NH1 engine. Recently I've begun having problems with it running and staying running. It will start, the engine then begins surging non-stop, then the engine stops after a few minutes. I have replaced the thermowax pin, cleaned the carb (jet and emulsion tube), and replaced the sparkplug and air filter. Any suggestions would be GREATLY appreciated. Thank you.
Where is that located in the carb? I only knew of the main jet. Thank you.

Under the screw
Also don't forget to make sure the air bleeds are clear.
These OEM carburetors are dirt cheap as this is as low as to be under $20 on some sites
