It just sounded like you dumped quite a bit in there. Since the plugs are out it wouldn't hurt to squirt several squirts in each cyl plus it has been sitting awhile but you're likely OK & I wouldn't sweat it. Alright after you wiggled the bulkhead it now has spark & I'd possibly get some fresh gas in the carb bowl & maybe plumb a can of fresh gas to the pump inlet till we get this thing going
