Where is primer button in 580.752951 pressure washer

does it have a primer bulb
if so press it several times until you feel a slight resistance
open the throttle up and pull the cord
the primer bulb squirts a set amount of raw fuel directly into the manifold

Hello,
This particular model is called a readystart engine, they do NOT have a primer or choke, if you are having fuel troubles starting there could be a blockage in the carburettor or fuel filter.

Hope this helps

hello,remember,it has to create vacuum [suction] to draw fuel in,the very fact you are using the 'primer' proves that it is only a fueling problem,and is simply not 'drawing in fuel on it's own.check that there are no 'crud' build up beyond the needle valve,is the air supply restricted?as no air in, 'NO FUEL'! recheck the list again,you will discover[happily] that you were on the verge of 'cracking it' best of luck, cheers.

You need to go to a small engine repair center to find the primer bulb that fits on your motor. It will depend on what motor and carburator you have. They are fairly easy to replace. The primer bulbs 'melt' or go soft because of ethenol in gas. You should expect to get one to two years out of a bulb so you may want to get an extra or two.

you have a plugged primary jet in the carb

The primer bulb has a pin hole in it:
This is what you need:

All local lawn mower repair / parts sources have this part in stock. This is a common issue with primer bulbs that you have to hold the bulb in so that it will run. When you do that your stopping it from drawing air through the hole in the primer bulb so it operates normally. Replace the primer bulb and it will be fine.

if you dont see a primer bulb then you must start it in choke mode after running out of fuel

This Power washer has a 3.75 hp Briggs and Stratton Engine. It does not have a choke but does have a primer bulb. You must depress the primer bulb at least 3 times to start the engine. The primer bulb is on the side of the carb. It can be black or red. If your still unable to locate the primer bulb please provide your ENGINE model number and I will provide you a link to a diagram for the location of the primer bulb.

Thanks for using FixYa.

It is a diaphram carb. Doe's the primer **** straight gas or does it have air bubbles in it? If it has bubbles in it then it is a leak in the fuel line.
If not then Unhook the intake fuel line and pump the bulb until all of the gas is out of it. Then pour the gas out of the tank and rinse it out with new gas. Pour in new gas and it should be ok.

My Kracher 2500 pressure washer has no pressure unless I remove the nozzle. If, I remove the nozzle and pump the trigger several times and quickly replace the nozzle it works fine until I release the trigger. Karcher (online) suggested I remove and clean the unloader which I did. It still doesn't work correctly. What another solution?
