Glad you’ve got it going, that’s positive.
As for the bubble, I wouldn’t worry about that especially if you’ve had it running ok. I’m sure when you’re driving gravity will do it’s thing and it will work it’s way up and out. An alternative way of priming everything is to suck the fuel up through the carb pipe, maybe less chance of an air bubble and it really cleans your teeth!
The pumps are pretty simple and there isn’t much to go wrong. I know people swap them for electric ones but they should be more than up to the job. While you're doing an overhaul I’d strip and inspect in, make sure the push rod is properly seated and replace the gasket.
I’d also replace all the fuel lines, I did this last week as I checked them while the carbs were off to do the steering box and they were cracked. I was very surprised as it’s only a few years since I last replaced them.
I’ve also fitted a one way valve in the line up to the carbs. Mine has never been a good starter and I’d put it down to the fuel in the carbs evaporating and the fuel falling back down the line so I’m hoping the valve with stop this. I haven’t tested it yet though.
