Well , the carbs are synced, throttle cable has slack and is lubed. I cant find any vaccum leaks so far. I cut my spring shirter and its snapping back just fine. All the slides move freely and have just a tiny bit of thread sticking out of the tops like they should. I am thinking its might be the floats are set too high. Its 26mm? from where to where? When I push down on the rack of carbs it stops. Not from the slides moving but from the carbs leveling out maybe? too much fuel at that angle could be the culprit?

Experience is something you don't get until just after you need it.
