    So I've got this B&S pressure washer. It had a 7.25 HP motor on it. It wouldn't run because the carb was gummed up badly. I hit the YouTubes and rebuilt the carb. Cleaned it spotless. New needle and seat, new float, the works. Put a new air filter on it and new plug. Pull the cord and it fired the first time !!! I washed the front porch and put a couple of tanks of gas in it.

    Today I pull it back out and I got nothing. I shot some starter fluid in there and it hit for a literally half a second then dead again. I took the carb back apart and checked everything. It all looks good. I know it's getting gas. There's plenty of oil in the engine. I also checked for spark. Looks good, plus if it hits on starter fluid why would it not hit on gas. What am I overlooking?

    Edit: one thing I did notice is that it's getting hard to pull the cord the more times I pull it. There's always a little resistance because of the compression but it seems like there's more than usual if that makes sense.

    Edit 2: I disconnected the water. I tried pulling it again. It was a lot smoother but still wouldn't fire.

    Did you check the fuel filter in the tank?
    The filter could be clogged.

    Small engines suck, I swear if everything could be pto off my tractor I wouldn't own another one for anything.

    My bet is the carb is gummed up again. They have little tiny passages that don't take much to foul up. Do you run ethanol gas in it? Did you clean the fuel tank when you cleaned the carb?

    Water hooked up it’s harder to pull.
    Water disconnected easier to pull.
    My money is on the pump shitting the bed and causing undo stress on the motor but I also have never won the lottery so my bets aren’t worth a shit....

    It builds pressure as it turns over. Every time you pull it equals a little more pressure. Just squeeze the handle to release a little pressure and it’ll be easier to pull.
    I too hate small engines. Got a 4 wheeler torn down as we speak.

    Make sure to put some StarTron or something similar in the fuel. Ethanol loves to destroy cheap small engine carbs.

    Briggs and Stratton engines are the absolute worst with ethanol gas. Throw the piece of shit in the trash and buy a predator to replace it.
    Otherwise likely issues are A) carb jet o rings that should never have been there are destroyed B) carb still fucked from ethanol---buy a new China one C) your valves are stuck due to terrible design and Ethanol. Sounds like it still has spark otherwise could be coil Gap, plug or coil. Try a new plug and only buy Ethanol free gas for all small engine.

    My old man removes the pull handle and uses a drill to start them. Much easier on the back.

    Used carb cleaner and shot it through every hole. Everything looked open. I don't use ethanol gas in my small engines.

    A good way to verify that you are actually getting ethanol free fuel, take 2 Mason jars, fill one 3/4 full of the fuel you want to test. Put about a couple ounces of water in the second jar and mark that level on the jar with the fuel. Now, add the water to the fuel and mix it a little and then let it sit for an hour or so. If the water line is at the mark you put earlier, then you actually had ethanol free fuel. But if the water line is higher, then there was ethanol in the fuel.

    Much easier to put each jar to your face and get a few good inhales. Easy to tell which is which from the smell.

    Or you get a little high and don't really care any more.

    This is exactly why I stopped dealing with small engines. Unless I have to for personal use. And then I have no patience.

    Check for water in fuel & clogged main/idle jet & compression test with a gauge.

    Does you pressure washer pump have a pressure relief/unloader valve of any kind? They can be a pita, after 6 years I found I hated small engines also! Most of the time if one of our 6 machines had this issue it was the Unloader not doing it’s job especially with hard to start issues, Does it vibrate the line at all while it’s running?

    The little shitty fuel pumps can also be a issue for not running if you haven’t ruled it out, but shouldn’t cause it to have hard starting issue like pressure is built!

    This^ creates a hard to pull. Most smaller washers, like the 2 I've had, don't have the unloader. You Need to keep the wand trigger open, as a by-pass, while starting, & during first 30 seconds or more running, or it will stall. Sounds like you have other issues though.

    That stuff doesn't matter. I have one that only gets ethanol-free. I've run it with sta-bil, I've kept the fuel tank full, I've run it dry. I still have to clean the carb once a year, no matter what. Even running them "dry", there's still fuel in the bowls.

    Meanwhile, I have a Toro push mower that is probably half full of varnish. I've never done a damn thing to it, run whatever fuel is laying around, etc. It hasn't been started in a year, but it'll fire on the third pull. Guaranteed.

    I don't know why, but some of those small engines just suck for carb issues.

    Yes and no...I've worked on friends' shit before that had the entire fuel system full of algae from leaving ethanol gas sitting in it, much more of a pain in the ass than just cleaning out the carb once a year. They all need regular maintenance, just a matter of what kind and how much.

    I have an old craftsman push mower like that. I won’t touch it for a year, I leave gas in it all winter, and like you, I run whatever gas is sitting in the shed. Fires up and runs like a sewing machine on the 2nd or 3rd pull. I won’t let anybody borrow it. It runs too good and is too dependable.

    Newer the worse they are...idle circuit restrictions and mandated emission type garbage has ruined them. They have engineered something with the needed performance of a Pinto into a frail half assed Prius. The problem is they still used the budget parameters of the Pinto to do it with.

    Yes, plus it would fire on starter fluid.
