Whats my best carb with little work and good performance?

yes good choice on your carb easy to tune if need be and will grow with your project and any racer thats really racing can help you tune with out a book as big as dictionary enjoy it they work good
fast mash of the petal has some hesitation I put the stiffer spring in secondary and will drive it tomorrow, If that doesnt make it better I will look at pump squirters.
