Likely you air to fuel ratio is too lean, runs mean and hot but under load dies. then floods the carb.
when it happens pull the plug ,
kill engine :
is there a lot of gas or none.
remove the filter and watch the action of the carb does it open and close easily is the filter clean.
try supplying it more gas turn the gas supply screw 1/2 CCW and see if it will stay running, if not add more.
( NOT the idle screw on the carb side w/spring )
By the way did a bit of water come out if not the clutch/pump may be binding or stuck with soap goop.back flush with hot water.

Motor quits when pull trigger


It's the spark plug more than likely. If engine turns but won't stay running its more than likely spark plug. If that doesn't fix its the gas. Empty gas out get some fresh gas.

The engine starts cold after 2 or three pulls, runs ok initially, but seems to have slightly less power. After a few minutes I can turn off the choke. When teh engine warms up and runs for about 15...


I would first try draining the carb bowl, if you look at where the choke lever is and look below that you should see a clear red tube with a flat head screw below that, if you just turn the screw out the carb will drain. If you still have an issue you are going to have to clean the carb.

Engine runs fine and then shuts off when I turn on sprayer


When the gun trigger is pulled, the back-pressure holding back the engine is reduced and the engine accelerates.

Your engine is dying when it should accelerate.

Good news is you have spark and combustion and fuel and the engine runs.

1) Check the exhaust port for build-up of carbon or dirt >>> the hot exhaust gas has to fly out of the exhaust port and if the port is clogged, then the engine stalls

2) Check the amount of fuel getting through to the carburetor >>> pull off the rubber hose entering carburetor from the gas tank >>> does gas run out freely? If gas does not run freely, then take apart your gas filter located just below gas tank

3) Remove air filter and see if problem continues. A dirty air filter can cause engine to stall since combustion requires oxygen coming through the filter. Replace the air filter.

4) Mess with the choke lever and see if you can find a setting where the engine works >>> our old power washer would never run when lever was moved to full throttle >>> we just left the choke lever at half throttle and the engine was happy

5) If above fixes don't fix the problem >>> the final suspect seems to be the carburetor >>> try some gun-out >>> maybe a trip to small-engine repair shop is required.

Engine runs great, when i turn the hose on it dies.if i hold the trigger and start engine it runs, as soon as i release trigger the engine dies


Make sure thre is no air lock in the system line. So first of all use a clean line to wash off and blow out any dirt in the spray gun.
make sure the engine is having good fuel and power it on to run and warm up . let it run over without any load on it . Now turn the hose on it and power it on slowing, do not stop but keep it running to power spray . The accumulated dirt might come off and make the run smooth after some time.

New Troy-Bilt 3000 psi - Very Hard to Hot Start


When you run the unit and shut if off, release the pressure from the spray wand before trying to restart the engine. This built up pressure will cause it to be very hard to start as you have found out. If it does not start on the second pull release the pressure again. Another option is do do what I did on mine. I simply put a pull tie on the handle so I can pull the trigger back and use the pull tie to hold the trigger open. Make sure if you do this, that you remove the high pressure orifice from the end of the wand before attempting to start the engine. Otherwise the pressure will come on abruptly and could injure you or do property damage.

Engine starts easily and then stalls, is hard to restart


If the engine dies shortly after start. Squeeze the spray wand trigger to release pressure on the unit. When restarting let the engine run for a few min(2-3 no more) to warm up, the unloader valve on the pump should keep pressure to a minimum. If the engine stalls or will not run you need to check your carburetor and clean it. BECAREFUL as FUEL is FLAMMABLE and there are small parts in the carb float bowl that like to get lost. A rebuild kit for most carbs is less than $8USD and a can of spray carb cleaner about$2-3. Install a fuel cut off valve($6) to keep the carb from gumming up again. Shut off the fuel when not in use or for periods of prolonged storage. Take a picture of the carb on the engine(my memory is bad) and during disassembly to assure you get it back together properly. The idle screw should be turned in(to the right)till it seats lightly then backed out 1&1/2 to 2&1/2 turns to start with. After starting the engine adjust for good idle and running buy turning in or out to attain the best idle. If this is helpful, Please leave Feedback. Thanks, SnugglePants

Pressure washer hesitates, does not start. Unable


get someone to keep the trigger pulled while you try to start it , its probably got presure trapped between the trigger and the pump.

alternatively turn off the water to the pump, pull the trigger to release any pressure trapped.

start the engine , allow engine to warm up, increase revs on engine then turn on water, should be ok then. Unless you have a problem with the engine that is!

Pressure washer sputters and stalls when trigger is engaged


Hi k2times01
It is a always a good idea to clean out the gas tank and use new fuel, however, this sounds like an RPM problem. Try adjusting the RPM up a tad and see if it runs better when you load it. If the RPM isn't the problem, you may have to clean the carburetor thoroughly.

Sounds like the governor is stuck. My pressure washer speeds up when it has to pump. Don't know if yours uses vacuum to trigger governor or direct linkage. Good Luck.

Pressure washer stalls out when wand nozzle is released


common for not starting unless trigger engaged as you are turning the pump as well as engine creating pressure,as for stalling pump has unloader valve which is probably in need of grease(use good silicone grease)this allows water to ciculate when trigger released.
