Sounds great. Crisp exhaust note can indicate good compression. You now have a nice example. Erratic running may indicate you still have dirt in the fuel system. Fuel not keeping up to carb bowl could indicate some blockage in the fuel line. I like to use gum out carb cleaner on a pipe cleaner to clean out those small fuel lines. Tells the story when you pull it back out. Pipe cleaners aren’t as easy to come by as they use to be. Loosen the carb clamp and with the gas shut off, disconnect the fuel line, catching the fuel that runs out on a paper towel or clean rag. Then slip off the carb and catch the remaining fuel on the towel. If you see any little specks you have more cleaning to do. If not, most likely, it just needs to get on a boat and run some. As you have had it all apart and disturbed it all, it may take some running for everything to settle back in. Tubs
