Default Re: starts but won't run

I haven't read all of your posts on this matter, but one thing caught my eye on your timing. You mentioned turning the points cam to where the points just closed. It should be to where the points just start to open with the rotor pointing to #1. This is just an initial setting. Actual timing is set by the spark lever on the steering column.
Is this a rebuild that has not run yet, or are you reviving an engine that has sat for awhile? If it was running before, leave the timing alone. That does not change from just sitting.
If you're trying to get it running on just one carb, remove the other one and make a block-off plate to cover the intake port. Just make a gasket or shim without the center opening and put the carb back on. Otherwise the engine can suck air around the throttle shaft and plate, through the float bowl, etc. and make the back cylinders lean.
Your carb fitting does not appear to have a line going into the carb so no problem there.
