briggs & stratton 5.5 HP quantum pressure washer won't start

any ideas what the problem might be? I have cleaned the carburetor and fuel lines. fuel is getting into to float bowl. I have also replaced the spark plug. once in a while when I am trying to start it, it will backfire. this pressure washer appears not to have been used much. the previous owner (original) owner said it only has about 3 hours on it.. all comments are much appreciated.

UPDATE: I do have it running now. I think the carburetor float needed to be adjusted. QUESTION! I cannot run the nozzle continuously or the engine will quite. IS THIS NORMAL? I have to turn the nozzle handle off for a few seconds (after a 10 or 15 second run) to keep it running. but it does work.

I did also replace the spark plug.  it's hard to tell if the spark plug is getting spark based on where I am located when I pull the starter chord (kind of hard to seek the spark plug).

well, I did spray starter fluid into the carburetor once before trying to start it. and it did start for about 3 seconds then quit. so it appears the carburetor is the problem? I did post one other video of the carburetor after I took it out. I am now getting gas in the float bowl. but apparently it is still not making it into the engine

Great tip on the "Brass Fitting" cleanout... I was having the same issue, and once I cleaned it out the Pressure washer fired right up! Thanks.

The float bowl is secured by a brass fitting / nut. This fitting has holes just under the threads and another hole at the tip which should allow gas to flow up through the pick up tube. Use a needle to clean it out.

If you have checked that it has a good spark, the next thing to try is to give it a little priming with fuel into the carb or directly into the plug hole, if it starts then it's your carb, if it doesn't, you could have a broken flywheel key or a bad valve! Try this, and I'll be glad to give you more help!
