How can gas get in with the oil on my 13 hp Honda pressure Washer engine?

[Chuck Bergman PC 18]

I have had a lot of odd problems since I started in this business in 1978, but I never had gas mix in with my oil???

Anybody understand this problem and have a fixing suggestion?

Thanks!

Sounds like there may be some crud in the needle valve in the carb. the gas trickles into the cylinder and seeps past the rings into the crankcase. Pull the bowl off the carb (shut the gas off first), pull the pin holding the float, and drop the float down. Be careful not to lose the needle. Clean the needle and the hole it came out of, and put the float back on. Before reinstalling the bowl, turn the gas on and gently lift the float so it's parallel with the carb body, the fuel flow should stop.

Don't forget to change the oil and flush it out before you try running it!

Do you shut off the fuel when not in use?

If you travel on a rough/bumpy road with the fuel on it will over fill the bowl & fill the cylinder. Ive had that happen afew times when the fuel wasnt shut off. In my case it never ran past the rings, just spit raw fuel out of the exhast untill it started.

Ya always shut off the gas when not in use.

Thanks everyone!

I did what you said Russ and that solved the problem!

I will also shut off the gas in the future too!

THANKS!!!

Run some "sea foam" (name brand) through the gas once in a while and it will clean out th carb great! It seems the new gas has a tendency to gum up faster.

I have a 16 hp Vanguard and fuel pump was messing up and was told to watch for gas in oil. I changed the pump and the oil. Working fine.

The Gas-in-the-Oil problem boils down to this.. the float valve in the carb of you ATV and your car all have a rubber tip, so they are unaffected by "bouncing" down the road..

Most small engine manufactures use the same carb manufacturers.. Mikuni and Walbro.. both have "saved a penny" on each, eliminating the rubber tip on the valve, making it easy to bleed, and necesary to shut-off the fuel valve when the system is not in use.. So, EVERYthing with a gas engine should HAVE a fuel shut-off, and you should meticulously use it.

one more thing..

Paul mentioned the "bad gas issue.. let me spell it out..

Oil Companies are "chemical salesmen"...

they've "profitably diluted" our gasoline with alcohol causing several problems..

first, it is lower octane.. remember we used to double the jet-size in the carb on our hot-rods to get 'em to run alcohol ?? AND we used to add a moth-ball or two to a tank of regular gas to increase the octane !?? (this was before catalytic converters for you youngsters.) ...well, that alcohol evaporates faster than ever, from our out-in-the-sun fuel tanks, and that sticky crap build-up that smells like moth-balls is screwing up the carb that sat too many weeks between uses.

Also, the worst of it all, you guys using the cheeper gas without stabilizer (or at least fuel conditioner,) are seeing more small engines with "stuck valves" than ever.

Glad to help, but I gotta go.
