1992 cb750 was running well, but had to take off carbs and separate them to replace a leaking fuel t-pipe o-ring. Put them back on, and now the bike only runs on choke, with the outer cylinders not running. I checked spark, replaced damaged pilot screw o-rings in those two carbs (here I thought I solved the problem), but still the cylinders are not running (1 and 4). I feel like I must be missing something simple that needs to be done. The carbs were cleaned while still connected to each other. I couldn't find any vacuum leaks at the intakes. Again, the bike was fine before I took off the carbs and separated 2 and 3 to replace the fuel t-pipe o-ring. Any ideas are appreciated. I know people will say to completely disassemble and clean...is that the answer? The spark plugs looked fouled and smelled of fuel, so gas is getting there.
Thanks
