Honda GCV190 won't run with air filter on

Hey all,
I just bought a new pressure washer (Simpson 3125-s) with a Honda GCV190 engine. It's a huge long story, but I'll condense. I assembled per instructions, hooked it to a water supply, and when I pulled the choke wire as directed to start it, it came all the way out...eg, not connected to anything. I took it apart and found the plastic lever where the choke wire goes into was broken off. After I fixed that and I was reassembling it, I realized that a tension sleeve in the air filter housing and two gaskets were missing. I got a replacement sleeve and I made gaskets from the proper gasket material, and put it back together and it still wouldn't start. I checked for fuel and spark...both good. I took the air filter off and sprayed some starting fluid into the carb (with the choke off) and away it went...with good water pressure from the wand. When I put the air filter back on, the engine shut off! I was able replicate this phenomenon a couple of times. With the air filter off, I pulled the choke on and it shut off (as I expected). 
BTW, I would have returned this nightmare of manufacturing by now, but the retailer's customer service made it worth my while to deal with this.
Anyway, it seems to run fine with the air filter off, but it shuts off immediately when I put the filter back on. Any ideas?
Thanks!
Pete

    Figured it out. It was just something else that was messed up when I got this BRAND NEW machine. Somehow the paper air filter that came with it got soaked with oil which prevented air from getting into the carb. I went to Lowes and bought a new filter, installed it, and it runs perfectly now. Un-effing-believable.

    My father had a Generac pressure washer that had oil all in the carb brand new out of the box. I drained the oil out of the carb and it ran fine after that.
    The oil on the filter on yours was changing the fuel to air mix. Glad you got it working👍

    I know this is an old post but my honda gc160 fouled the filter right before the intake valve broke. Did this happen to you?
