SOURCE: Foaming in pump oil window

I dont know which comet pump you have, but it is just easier to get a new pump from one of the pressure washer companies on the internet and they sell them on ebay. You can also probably get a better pump that will fit your engine as well. Also, have you tried just changing the oil and not fill it too full? On my 5000 lb washer, if i fill the oil too high when I change the oil, it will foam some. Hope this helps you, Rick

SOURCE: Northstar PW shuts off hot if washer is moved. Honda engine

Being petrol driven, it may have a mercury kill switch which puts a ground on the ignition circuit stopping the engine if you move it. Perhaps for safety in case you overturn the unit somehow.

Engine runs fine, pump works, but it's not kicking the burner on ?


The first thing I would check is spark on the electrodes in the burner, if you pull the transformer down from the bottom of the burner you will see two springs that touch metal poles in the bottom. You are going to have to have someone else run the machine in cold water mode (these machines will create spark in cold or hot water mode) and holding onto a long insulated screwdriver you are going to get about 1/4 inch away from each of the springs and see if a spark comes across the spring and the screw driver. Be very careful in doing this, you are playing with a lot of power. If no spark then this would indicate that you have a fuse blown or the transformer is bad. You would then proceed in checking power to the transformer. If you are getting spark then it is going to be one of the safety systems that is giving you a problem. Let me know what you find out.

The injector might be worn out or have something inside of the valve causing it not to ****. If you are using a new high pressure hose or a longer hose this may also have an effect over the injector not working.

I have a northstar pressure washer 2000pw serial #03005610 item #157754b someone has took carb off and u was wonderin if u could give me a blowup of how the linkages and springs go ?


You will find your information by looking for model number and code of engine. Look on the fan cover, valve cover engine block or tag directly on the engine itself. Example would be Honda model gx340 from starter of engine. Then check google or mfg. web site for manual showing governor linkage. Norhstar uses several brands of engines. Good luck

Smokes bad when burner kicks on


Hey mate,

What brand of burner are you running? I am a Karcher Tech but they all work on the same principle,

Your burner is getting to much diesel/kero, most have little flow swicthes on them to tell them to pump fuel or spark when there is water present in the burner coil, if this switch is faulty or getting a faulse reading then it will tell the unit to pump fuel when it is not needed and this will cause very excessive smoke for the first few mins when the burner kicks in...

If you have the excessive smoke continuously(even after 10 mins of continous use then it is probable that your fuel pump/system is running to rich, these units need regular servicing and adjustments as fuel nozzles/components wear,

There is alot of precise adjustments and checks on these units and i would reccommend getting it checked by a qualified tech, as when there is heated fuel and spark these units can be dangerous!

Hope this helps

Regards
Brad
