Ok, one thing I forgot to mention is that all the fuel seems to be going to the bottom carb, top carb stays dry. They're both set at exactly the same adjustment.
 
Well----If the top carburetor is dry there is no fuel going into the top 2 cylinders.----AND NO OIL.----Find what is wrong and make repairs before you start the motor again.

Right. Sorry I wasn't clear, the fuel problem happened after the carb rebuild, so maybe there's a fuel line that isn't tight or something simple. But as far as the first problem, do I need a special tool for checking correct timing or not? There's like three different marks on the flywheel, someone before me may have been messing with it.
