My powerwasher(2500psi) with a B&S QUANTUM 120000 gas motor will stall when hot, pressure drops significantly, and is hard to restart. When it does re-start, it stalls again in 2 minutes. This behavior started recently after working fine for 2 days. I changed the oil-no difference.

I assume you did plug and filter change. Check the plug wire for fire when hot or problem occurs; it should be pretty visible- don't shoch yourself. Check that fuel is reaching carb, check tank for debris. You may need to have valve adjusted. Good luck.

Hi there,

It seems there must be some coil burnt inside the motor, now you need to check that burnt.

Thanks

A practical alternative to replacing parts at random would be to take your vehicle in for a comprehensive diagnosis to identify the real cause of the problem(s).

Portercable Pressure Washer Model PCH2401


when the trigger for the wand is not pulled , there is a pressure relief valve that bypasses the water in the pump and so there is no pressure until the trigger is pulled again.
with the pump getting hot and not being able to pull the motor to restart, it indicates that that pressure relief valve has jammed ( faulty ) and the pump is running at full pressure all the time
That will heat the pump and stop the engine from restarting
That valve is where I would start looking for a problem

I have a 92 Storm GSI. When driving down the road the car stalls like it is out of gas then starts running. I have replaced the fuel filter, pump and relay. Any other ideas?


For the age of this car it is a combination of both the fuel filter and pump, i owned one several years ago and found that the gas tanks are prone to rust inside, if you have replaced the pump and filter you may want to drop the tank again and check the screen on the pump if it is brown you have rust in the tank: another problem i had ( if you bought an oem pump ) they tend to slip out of position, you can tie the pump it place so it doesn't move......

Excel powerwasher with B/S motor. Will start and


Is your air filter dirty? If so replace it. If it is still doing the same thing try this:

Turn off the fuel valve, or drain the gas tank, then place a rag under the bowl to catch the gas that will run out (the bowl is under the carburetor). Loosen the "nut" that holds the bowl on, and after the gas has stopped draining remove the nut and bowl. Blow out with compressed air, if available. Put the bowl back on and try to start it. If it still will not run off choke, the carburetor probably needs a good soaking or to be replaced.

6hp Johnson outboard stalls & quits


go to an auto parts store and get a can of gasoline additive called seafoam. Read the label so you know how much to add to your 6 gallon tank. This stuff works wonders on outboard motors.

Wagner electric asincronous H 100L4 1982 motor MK-250. Compressor will start, get up to pressure okay, but once pressure drops it will stall on restart and trip out mains.


The overload trip is is not rated high enough for the load. When the compressor starts form zero pressure their is little load on the motor. It then pumps ok to the cutout pressure under gradually increasing load. When it tries to start on the intermediate pressure the load is too great as the motor drawers a higher current on start-up and has the additional load of the higher pressure. You have a 15 amp appliance running on a 10 amp circuit or similar depending on your countries supply voltage.

When i start my 92 geo tracker, it starts fine but about 5 seconds later, the idle drops significantly. enough so, that the car sometimes (usually) stalls and i have to restart it. it also stalls...


this is cause because the ISC is busted or can not open enough to keep idle at 800 rpm.

ISC , idle speed controller

but....
the car has a TPS switch on the throttle body.
if it fails to close at idle the ecu will never attempt to set idle.

or
car could be flooding. (too much gas)

you did not say if motor is 8valve or 16v and they are quite different EFI systems.
