Troy Bilt 2500 PSI 2 3 GPM Gas Pressure Washer

[cvfncrew]

Okay Experts,
My new Troy Bilt 2500 PSI 2 3 GPM Gas Pressure Washer worked for a few months with no real problems. I did not use it for a month or so and now the motor stalls after a few minutes of running. It has fresh fuel air filter and oil. Any ideas?
Thanks
CVF

Carburetor - its always the carburetor. The gas we get these days gets old and gummy real fast.

It's dying after a few minutes because the bowl is running out of gas and can't fill fast enough to stay running. Take the carb apart and clean every little hole the best you can with carb cleaner and an air gun or better yet, get a new one.

I own a small fleet of gas powered stuff and we just change out the carbs at the first sign of trouble.

Thanks Randy, I will try that.

This is just a waste of good carburetors. Clean them first! My Willys, scooter, and motorcycles are carb'ed .

+1 on the fuel supply. From the tank to the bowl. You'd be surprised how long a small engine will run on just what's in the bowl.

I wouldn't even take the carb apart if the engine ran well. Just the bowl and hose. There should be a fine screen filter somewhere.

How long is "a few months"? Warranty? Is the plug wet when it stops? Does it have spark?

Depends on what you pay your help vs the cost of the carb.

It is a gamble to pay your help to pull off the carb, clean it, put it back on only to find it still doesn't work perfectly - that's why we decided to just replace them when we go thru the trouble to take half the engine apart.

Okay guys,
I drained the gas, checked the fuel lines, checked the fuel filter, cleaned the fuel bowl in the carb, used the air compressor. Put it all back together with new fuel and now it wont start at all. Sounds like its not getting any fuel.

Sounds like the needle and seat are sticking closed not allowing the bowl to fill. Take the carb apart and check their operation. You can also remove the bowl, blow in the fuel line with your mouth and move the float up and down to see if the needle is opening and closing.

Or, just price a new carb, replace and get back to washing. This is why we don't waste time on $75 parts.

Next step is to read the plug. Dry, no gas. Wet, get a new plug or clean the old one thoroughly.

The reason I wouldn't jump to buy a new carb is that I've had other things go wrong, like the coil.

95% of the time it's the carb.
+1 on making sure the needle and float are operating correctly, that's 99% of carb problems. It's where the gas sits the longest.

Air - fuel - spark

Take out plug, replace wire and set it on the head. Slowly pull cord to check spark.

Remove air filter to eliminate air issue.

Spray some starter fluid in carb. If it starts and dies quickly, see above posts.

10% ethanol gas is the cause of your problem. It ruins small engines that are infrequently used.

What a coincidence. I post on this thread about small engine problems and wouldn't you know it, I have a problem. Last weekend I fire up the weedwacker and it runs terrible. Only will run with the choke on halfway. Now that I think of it, it ran bad when I put it down for the winter.

Cheap little diaphragm carb. The diaphragms wear out and they can't pump enough fuel - the only way it will run is when you cut off most of the air.

Go on ebay, buy a new one for $25 including shipping, throw on some new fuel lines ($5) and it runs like brand new.

I've had several small engines develop that syndrome. It always boiled down to dirt in the jets.

I remember a time when I had the kart out at the track. I'd get a half a lap and the thing would not run. I came in, fiddled around, started it and it would go like hell for.... a half a lap.

Finally, I tore it down far enough to find Dalmatian dog hair (very short little spikes) in a passage. What had happened is that the funnel I used had the dog hair in it. With the little bit of oil used on 2-cycles, the funnel was just sticky enough to hold to hairs.

They got thru to the innards. About 3 of them.
