On my birthday bike ride, I was only able to use the small chain ring; the front derailleur wont shift to the large chain ring. Yesterday, I had the opportunity to tune it for it to work on large chain ring. The lack of large chain ring slowed me down on flats and going downhill.
I spent almost 30 minutes trying to get the fd work right. Armed with a 5 mm allen wrench screw driver and pliers, I tried my luck. First thing I did was to get the slack off the cable, Then trying to get the shifter a little bit out by turning the low screw clockwise until I got the chain go to the large chain ring. However the chain was jumping off the ring. So I had to turn the lower (high screw) about 4 x so that the limiter will prevent the chain from over reaching. After wards, I tried the shifter and it would not shift again. I had to turn the lower screw cc about 3 turns to get it right.
I think did trial and error of the adjustment about 4x; I nearly gave up to bring the bike to the mechanic. The patience paid off and was rewarded with a functioning front derailleur.
