Review on 45 Speed Steel Gauge for Gyros 22010 by David Padilla

I work with mowers, mostly carbureted systems, some fuel injection but 95% carbureted. The new square plastic carburetors from Briggs and Stratton have a .013" main jet. Almost all others are about .028" in diameter. Smaller ones tend to clog and make starting impossible. Sometimes I drill problematic ones down to .020 to keep them from clogging. The good news about this set is that they are ok so i can always get what i want i use them all the time.
