Your unloader valve is stuck in your water pump. Remove it, lube the top o-ring with silicone grease. Then reinstall it. Use pump guard additive to prevent this problem from reoccuring.

I have a Honda 5 hp XR2600 presser washer, I have trouble keeping it running without the choke on. It starts right up, but it need the choke on to keep running.

I would try empting the gas out of the tank just to make sure you don't have some water in the gas. If that doesn't help you have a carburator that needs to be cleaned or maybe rebuilt.

My honda gc 160 pressure washer i have to take the tip off the wand to get it to get to have pressure.

With the tip removed you have pressure? or you have flow. Usually, with no tip you have very little pressure with lotsa flow. Sounds like tip clogged up. Have you tried other tips? If you hold the tip up to the light you should be able to see through the oriface.

At what period of time parts like chain, spark plug, battery, airfilter , brake shoes etc., need to be changed in order to get proper mileage and pickup. problem: my motorcylce gives around 45km/ltr. are...

Keep the tyres at the correct pressure this is the main cause for mileage problems.. Chain keep oiled so there is low drag, plugs as per book, ari filter dont let it get too dirty, brakes make sure there not over adjusted and causing drag, battery only if its discharged all the time it can take some power. oil keep it clean.

Pressure washer worked fine and suddenly no

If you remove the tip, will it work? If so, unloader valve is sticking and needs to be removed and lubed with lithium grease.

Pressure washer - can't figure out soap

Dont use your mouth youll get poisoned, soap will only come out when there is high water flow, ex. with soaper tip (the one with the bigger hole) or no tip. When you have high pressure tip on it will not work.
