Don't waste time on gas additives. Simply (a) run fresh gasoline very time, and (b) schedule to pull the head and scrape the carbon every 100~200hrs.
Q.
You might get 1/8th of that run time before main jet gets clogged. I've heard that even TCW-3 can help stabilize the fuel and also keep the carbon deposits to a minimum.

You'd be surprised by how simple they are and how few parts they have. You'd also be surprised by how simple they work.
Main jet is usually a single fastener to remove the bowl, and then the jet screws into the bowl. Easy as pie, you dad didn't teach you how to do it because it was not an issue before they started irishing up our gasoline.
