544 missing problems

I have a I-544 that has been giving me lots of problems lately. It started with the fuel-shutoff seleniod. I replaced that, then it would run but would miss considerably and puff black smoke. So I replaced plugs, distributor cap, points, condensor, and put a new sediment bowl on. This did nothing for it. In the process of all this though, I did discover that if I turned the gas off at the sediment bowl, just before the carb bowl would run out of fuel, it would run great for about 3 or 4 seconds before totally running out of gas. So this told me I had a fuel/air problem somehow and not spark. So, I got a carb rebuild kit and overhauled the carb, even put a new venturri in. Old venturri looked bad. Put it back together and tried it. Same !@&@#$% thing! I discovered that if i put the venturri in upside down it will run smooth but the choke has to be out and when under a load you can't get it out far enough to keep it going. But with the venturri in the right way, it just misses all the time. I am almost convinced the carb is ok, i've been all through it now! The pump is oviously pumping fuel. I am stumped now. Especially since turning the gas off makes it run normal when it's just about to run out of fuel. Does anyone have any ideas? Thanks in advance.
