fuel supply

93 750 gixxer, broke my petcock trying to replace the seal in it. Tried really hard not to, took my 45 mins to break the white metal housing.
Took a petcock off a friends spare katana tank, issue is it only has 1 fuel outlet.
Installed on my tank, ran 1 line to a "t" and then to both inlets on the carbs. Ran like crap, bogged, leaked fuel, #'s 1 and 2 cold while 3 and 4 hot.
figured too much fuel so I ran 1 line from the valve to the inlet between 1 and 2. Blocked off the one between 3 and 4 and ran great after a few mins, revved fine. In the garage. Put panels back on, went for a test ride, made it 150 ft before it started running like crap and stalled out.
Anyone have this issue? Am I running the feed line to the wrong inlet? Should I unplug the inlet between 3 and 4?
I've read where replacement petcocks have only the 1 valve, any idea what I'm doing wrong here?
I've found a source that offers replacements, but with an adapter plate and only 1 outlet. don't want to put out the dough if im going to have the same issues, of solve what the problem is now.

Thanks in advance.
