Why can't I start my power washer?
Let's start with the basics . . . if it has one, make sure the fuel petcock (shutoff) is on. Is there a choke lever? If yes, try choking it for 2 pulls, then open it and retry a few pulls.
Is there a primer button? If yes, press it 2 or 3 times and retry starting.
Remove the spark plug and see if its wet or dry.
Dry means no fuel thru the carb.
If dry, the float/needle is most likely stuck OR possibly the jets are blocked with corrosion. Both of these usually occur after a long storage period, but could happen sooner. The carburetor will need to be disassembled to be cleaned.
Wet means it's flooded OR no spark.
If plug is wet, check for spark at the plug by holding the base against the crankcase and having someone pull the rope gently to spin the engine thru steadily. No need to spin it at 3000 rpm without the plug in it. Be careful, as sometimes the spark will ignite the fumes from the engine as it turns over and can create a blast directly toward you. If there is a strong spark, pull the rope a few times to "clean out" the excess gas from the combustion chamber, reinstall the plug and pull the rope again to try starting it.
If NO SPARK, the coil could be bad and in need of replacement, but this is highly unlikely.
If none of these cure the ill, I recommend finding a service agent for the unit.
