Well I am not sure how long you have been driving with carbs but they usually require some maintenance to keep them running well,
So I think you will want to learn how to adjust them at some point. But it may be worth the money to have them set by someone that is knowledgeable and go from there.
You can by a air fuel gauge and have it installed. Worth the money for sure. It will tell you when things are going amiss with your carbs before you get to the point of having no power.
Search for the weber tech guide and buy a copy. It is an old book but has the best information on adjusting carbs. You will also need a snail gauge to ensure the carbs are balanced.
Pull your plugs and see where they fall on the chart below.
