So here's an update. I ordered a carb kit off of ebay and I cleaned and rebuilt carb. I soaked it in solution overnight and then rinsed with water. I then blew out all passages with compressed air. Put it all back together and it only runs on full choke (when it runs that is). Using carb cleaner to start produces mixed results. Sometimes it starts the engine, and sometimes it doesn't. So I took it apart again and adjusted the float according to spec in the Wisconsin service manual (1-5/32 inches) and cleaned everything out again with spray carb cleaner and more compressed air. Put it all back together - but still same result - won't start easily, and when it does start, will only run on full choke. In fact I have to HOLD the choke lever in place at full choke, otherwise it will move on its own and stall.
Also the glass fuel sediment bowl strainer under the tank won't fill up when I tighten the fuel lines. I also replaced that part as well - a brand new sediment bowl. Just for kicks I put the old bowl back and it too won't fill. Only when I loosen the fuel line somewhere and let air in the line will it fill the bowl.
I have taken this carb apart 3 times (including to rebuild it) and did the same thing each time: sprayed carb cleaner in all ports and passageways and then used compressed air. I've tried adjusting the two adjustment screws (the idle screw on top and the high speed screw on the bottom side). I don't know what else to do. I can take this thing apart a hundred times and still have the same result. What could be the problem?
