So I buy a new bike, works great, no complaints. Then I decide to put a K-edge chain catcher on it using the FD braze-on connection--the FD falls and I don't know how to align it properly.

I bring it to my LBS, the guy spends maybe a minute working on it and says I'm good to go. I go to ride it and it still won't shift into the large chainring, yet he got it into the large chainring just fine.

It's Shimano 105, in theory I know how to shift up but it's not working for me. Even if I push the shifter as far to the right as I can and to where I think I'll break it, it just rubs the chain and the chain doesn't make the jump over.

Someone teach me the proper way to shift it lol. (By the way, the cassette shifts just fine, it's just going to the larger chainring that doesn't work for me.)
