I have an Excell VR2320 I use for occasional cleaning outside rental homes. Lately, the engine has been dying when I let off the trigger. Everything else works fine, pressure is good, responsive, etc, it is just a pain having to restart the engine everytime I let off the trigger for more than 4 seconds. On the internet, they say this might have something to do with an unloader valve setting.

Can anyone tell me where this is located? There is a round adjustment the size of a quarter, just below the engine in the back, with a square indentation that a 3/8" ratchet extension might fit into. Is this what I would need to adjust? If not, what exactly is that for? I don't see anything mentioned in the manual regarding that, and none of the sales clerks in big box retail stores have any answers (no surprise there).

Thanks.

I have been told, if the unloader valve goes, you might as well replace the whole thing. I have an old Dayton PW that dies when the trigger is released. Took me a week to get the thing running this year after it sat for a couple years!

Nick, if you know how to fix this relatively cheap, let us know!!

Briggs & Stratton. I read a lot about the problems associated with B&S and later they started using Honda engines. It makes sense that the valve is in the front with the high pressure output. Thanks.
