Brigs 6.5 on VR2500 Powerwasher

I have a Ex-cell Brand Powerwasher with 6.5 Quantum Engine. 123K12-0134-E1-05042157. Im thinking Im having lean carb problems. Heres what it does .Turn hose water on and have wand in hand and pull the trigger for easy starting .I choked the motor and it starts always on first pull . I turn choke off and let it idle the wand trigger is let go and I set engine speed at about 3/4 I try to pull trigger on wand but it wont pull. This is just one problem .My fix was to just hold the triger open the hole time. So my second problem is that the engine quits about 7 min to 10 mins after running. It also puffs out smoke out the exahust at that point to . What ive tried was to look at spark plug its really light colored . I changed the oil cause it gets really hot to .I took the carb bowel off and cleaned float and around .I shot carb and choke cleaner on float and up that little aluminum square and pointed thing with that fine wire on it . And drained the gas and put in new gas. I did this one thing I left the gas cap off and it ran a long time but it got really hot real hot. Thanks for the long read . Any help would be great.

Does it run fine when it runs? Will it idle steadily?

It sounds like the gas cap vent is plugged, but I'm wondering about the heat thing. Are you certain it is getting hotter than it should? Air cooled engines run pretty hot. Does this one have an adjustable pressure knob?

Yea I was thinking the same thing cause when I was at 3/4 speed the I was at about 6 mins and still going strong . Then I put the capo on at about 1.2 tank and it ran about 8 mins then just quit. Looked in to tank pulled the cord and it started right up . So whould the cap make it run lean then . When I say hot it just makes a lot of noise and a puff of smoke at then end when shut off. And just feels hot then. Dang you think it s the cap . Im off the to hard ware to get one I got about 1500 feet of concrete to spray . Thanks for the info . But I still got a sticky wand that wont spray after I use it the first time .

Yes the cap can cause it to run lean, and it does sound like that is the problem.

I don't know about the wand...sounds defective.

Yep I have one of these pressure washers too. I realize I'm bringing this thread back from the dead, but I was having the same problems as JustOneBoat... All I had to do was blow out the vent hole in the gas cap, then it was still running a bit lean, (had to leave choke on about 1/2 way). So I pulled the fuel bowl, and blew out the little ports in the screw that holds the bowl on. Runs like a champ now.

As to the wand trigger issue, the original one is pretty flimsy in the trigger! the part that engages the valve flexes too much and can't open the valve under pressure. I found a replacement at Home Depot that is rated at 3000psi as opposed to the original that was only rated to 2700psi..
