Ok, long time overdue. Gave up on AF screw, stuck good. good news is bike is finally running. Took forever to get the time to finish what I started. Fuel tank was rusted, sealed it, then had no spark or fuel, not sure which it ended up being but picked up a new battery, thanks for the recommendation by dragmaxster, tinkered with the fuel lines/pump and hooked up new battery and away we go. Need a carb sync if someone's local to so cal. Hoping the "backfire" out of the front right carb is a sync issue. Slide was sticking but took it apart, wiped it down and checked the seat on the diaphragm and works fine now. Hope to be done for a while and enjoy the ride.
