BTW, I don't understand why you're adjusting anything while you're in the smallest cog/chainring combination front and rear. That's technically an "illegal" gear combination in 8-speed systems, you should get unpredictable results since the chain is really way far off the limits of chainline goodness.
Thanks Anixi,
I am infact using an 8 speed sachs chain. (maybe that has something to do with it. not being hyper glide.)
The issue of crossing the chain...
What I mean to say is that I put the chain furthest right, then furthest left. Not crossing the chain. I only use the first 2/3rd of the gears for each chain ring, keeping the chain line straight. Sorry I wasn't very clear or got it mixed up. I'm adjusting the FD to the furthest right (big chainring/small cog) and furthest left (small chainring/big cog).
So that said, any other ideas as to why the cable pull is insufficient?
Thanks,
