Pull cord stuck open

Most likely the recoil spring broke. The engine cover has to be removed to repair this. If you are not mechanically inclined, it would be best to take it to a local small engine repair shop. Proper replacement involves knowing how many pre-wind rotations is required to properly recoil the rope. Some things are just better left to the pros.

Motor runs but no water pumps through

It's possible that the 'unloader' in the pump is plugged. A local small engine repair shop can replace it (generally under 50 bucks). Of coarse you have the hose hooked up to it and the water on.

Broken pull cord

Pull cords can be purchased from your local hardware stores. If the handle just broke off, and the cord is fine, the handle itself can be replaced.

If you are uncomfortable performing the work, just look for 'small engine repair' places in your yellow pages.

Parts are easy to find for honda engines at the small engine shop and on the net. All that you need do is to locate the model and spec number of the engine itself and go to the link below for your parts. Some honda parts are available in assemblies only, like the complete starter. Be sure to check ebay for aftermarket parts. You may save some money. Look for a "starter pawl assembly kit" .

No spark on B&S industrial engine fitted ti Stephill generator

Always have a new spark plug handy to determine if faulty plug when no or weak spark. If your engine has an oil alert, disconnect sensor wire and re-test. If still no spark suspect spark plug boot or coil. New or used coils are available at small engine repair shop. If you have access to growler (used for testing armature), by placing coil on growler with one leg on each pad, you can test coil for signs of life. Good luck

Blue and white smoke coming out of engine while using water pressure gun

That means the engine is burning oil. Unfortunately that means that the piston seals are bad and need to be replaced. Its not terribly hard to do, but you will have to tear apart the engine. Unless you are comfortable doing this I recommend taking it to a small engine repair shop.

Bought unit new last summer. Used it once last summer and once this year. It started fine both times. Today, it will not crank. I have replaced the spark plug, checked the air filter (it is clean), gas...

Unable to crank? Do you mean unable to start?

If you leave gasoline inside tank over long period of time, that will 'gum-up' and ruin carburetor.
To prevent problem, put additive in gasoline or empty gas from tank:: under gas tank should be a hex bolt that holds up gas filter > loosen bolt and drain gas.

Starting the engine:
Take off air filter and spray WD-40 directly into carburetor.
Start engine, engine should fire on the WD-40 accelerant.
If engine fires but does not keep running, try spraying WD-40 into carburetor continuously to see if you can keep engine going.
If engine stops each time after it no longer gets WD-40, then carburetor is bad or gasoline not getting to carburetor or gasoline is bad.
Try fresh gasoline.
Do not turn small engine on side or upside down or oil will get into carburetor.

Check gas supply: Go to gas filter under gas tank. Pull loose rubber hose that connects to carburetor and see if gas comes out rubber hose.
If gas is flowing to carburetor, then carburetor is gummed up.
Small engine repair might suggest 'gum out' or have other suggestions ... but you may need a new carburetor

If engine will not fire on WD-40
If engine will not fire on WD-40 at all, then spark coil may be bad or exhaust port is clogged
Check screen that covers exhaust >> is it covered with carbon and dirt or can air pass through it easily?
Check spark
Remove spark plug
Put spark wire back on spark plug
Hold spark plug by rubber spark cap so hands don't touch metal part of spark plug
Touch spark plug threads against hole where spark plug was removed >>> metal to metal so it conducts electricity
Pull start cord and look for sparking between spark plug threads and metal of engine (don't look at the spark gap ... look where metal meets metal
If you have no spark, the spark coil is bad >> time for estimate from small engine repair shop or get your part number and order replacement

I let the pressure washer sit over the winter and now it will not start and the spark plug gets all jucky. I want to learn to repair and clean the unit myself. Where can I get info to do this?

There is a great little book on small engine repair that you can buy on ebay for less than $10
Its called “Small Gas Engine Repair”. Also there a quite a few videos on YouTube that have are very helpful. If things look a little gunkey then the gas may have enameled up causing the carburetor to clog. I would drain the old gas out then remove the bowl from the carburetor and then check the float to make sure it is going up and down freely. Put a new plug in it, even if the gungey plug has spark. (They can behave different while under pressure. Check the oil, Gas it up and giver-a-go.
Hope this helps.
Have a Great Day
