Question Campbell Hausfeld Power Washer mod pw460

My gas washer works fine, plenty of pressure but have to hold the trigger on the wand down to start the engine to get it to work & when I release the handle it kills the engine. This started after it had been in winter storage. Any ideas what could cause this problem? Put a new gasket & O'Ring kit in the pump a little over a year ago but it work fine up to now.

The unloader valve is stuck. You'll need to take it out, clean it and lube it, and possibly replace the o-rings on it.
