engine stall

[marco]

I was searching the forums and could not find an answer to my question. My power washer stalls when I pull the trigger. It starts up no problem but will bog out when I pull trigger. 4.2 gpm mi t m 4000 psi .

Might have a dirty carb or trash in the fuel line. Might be dirty or loose air filter

I had a similar problem a few months ago. Turned out to be a bad coil.

Spark arrestor if the tuneup doesn't do it

How about some more info? Honda GX390? How old is it? Has it sat for any length of time?

I had the same problem today and it ended up being a bad gas tank cap. I would of never guessed that. Take the gas cap off the tank and run it see it dies on you if not then it's the cap. Hope that helps.

The machine is a 16 hp mi-t-m briggs and stratton 4.2 gpm 4000 psi. The motor stalls when I press the trigger especially with my surface cleaner.( whisper wash) . It may be the unloader but I dont know how to adjust. It doesnt happen as much with the lance. Thank you guys!

Get one of these... http://www.harborfreight.com/inline-ignition-spark-checker-69014.html
Check each side for spark. The Vanguards have a wire that joins the coils to the ground terminal for the ignition. The wire has a diode at each coil to isolate the coils from each other. If a diode burns out, one coil will short out the other.
