Pump will not unload.


Hi if it stop when the trigger is pulled the issue is with the motor.
stopping is caused by , low revs on motor or low compression or poor spark, sometimes faulty carby.
change spark plug , adjust valve ( when valve has some slight side movment it is ok if up and down , it should be tighter (valves usually under side cover near top ) increase revs a little ( make sure revs dont get rough when running high) set max revs to when the engine still runs smoothly at max.

Idle problem


There is an arm that runs from the governor arm to the carb. There should be a long spring on this to even out the revs. If that has come off it can cause similar problems. If you have checked/reset the governor arm on the pinion that comes out of the crank housing and the spring is in place I would think the only other problem is the actuator that operates the governor arm pinion internally. It is a strip down job to check it, but there is a (plastic?) cog that runs of a gear on the side of the crank shaft. This has a weighted pusher that moves with engine speed to move the governor arm. I have seen a couple of engines where there is wear and the weights have popped over the 'top hat' pusher stopping it moving freely and causing full revs. If you're not confident in stripping the crank casing down (you can leave the piston and crank in place to check the governor mechanism) then you should definately take it to a dealer or experienced technician.http://www.honda-engines-eu.com/engines/PartSelection.jsp?model=GX390K1&type=BJ&npl=10ZF601%20&lang=EN
Position 9 is the governor assembly.

Motor will not turn over. Checked air filter compartment to find 2 oz. of oil and filter soaked.


Not sure if you mean engine will not turn at all (locked) or engine will not start. The engine may have been on its side causing this condition. Clean carb and filter of excess oil. Remove spark plug and clean cylinder and plug of oil that may have entered causing locked condition. Replace oil lost from crankcase. With spark plug removed and kill swith on off, pull rope to blow out oil and verify that motor will now turn. If it still does not turn could be lock rod to crank or faulty pump. If engine had very little or no oil in crank and was run, suspect locked crank, however if your engine has oil senser, this condition would have prevented engine from starting. If you mean that engine will not start, low oil senser most likely preventing start due to low oil. Good luck

My 13 hp honda power washer has a miss when it's not under a load. Is it a fuel or spark problem ?


Most likely fuel / plug. Easy to check. While running unloaded and miss-firing, try applying the choke just a little to increase fuel mixture (make run slightly rich), if clears may need carb kit. If it gets worse with slight choke running rich or plug faulty. Before you change parts try using premium fuel. If runs better problem solved.

Pressure washer stalls


Pressure washers work under very dirty conditions, no wonder they encounter engine problems. Here are a few pointers from a former pressure pump tech. The unloader is a source of engine overloading however this can easily be checked with a pressure guage attached to the gun with a tee fitting having the guage and the normal tip used for the unit. The pressure should never rise over rated pressure. The pressure should drop considrably when trigger is released. The life of the pump and engine can be increased by setting max pressure to 75% of rating. Most engine problems are from following conditions:
Leaking or misadjusted valves; clogged muffer /spark arrester; weak spark coil that is about to fail completely; kill switch/oil sensor wiring and or sensor mal function; gas cap not venting properly causing vacuum in tank and wet or dirty air filter.
All these problems easy to check, fastest repair is to disconnect oil sensor wire to check oil safety system. Then temp replace coil with known good coil. Loosen muffer bolts to check for clogged muffler. Temp run engine without gas cap to check for vacuum. Finally if everything fails, run the engine with carb cleaner spraying directly into the intake. If the engine continues to run with carb cleaner then the problem is fuel delivey and faulty carb. enjoy

I have an SDMO generating set with a Mitsubishi S3 L2SD engine it is supposed to run at 1500 rpm but goes up and down depending on load, if I set the rpm at no load to 1500 as soon as a load is applied the...


Set the no load revs such that you get 51 Hz out of the generator, at 80% load this ought to give you something like 48.5 Hz with less than a 3% drop in output voltage. If not, you might have governor problems but I'd try servicing and adjusting it before replacing anything other than filters.

Cheers,
Carl
