Shimano 105 front derailleur, Sugino crank and large chain ring, chain touches the derailleur cage Why does the chain on Shimano 105 front derailleur with Dura-Ace downtube front shifter touch the derailleur cage with the Sugino large chain ring?

The outer limit screw does not move it far enough. I have set the outer limit screw on furthest out I can set it. I don't see any other adjustments anywhere on the Dura-Ace downtube shifter nor on the derailleur. 

There is plenty of play on the smaller chain ring, but I don't know how I could move the whole front derailleur further out? Any ideas? 

It seems like the Shimano front derailleur/shifter has sort of 2 speed indexing, maybe this is the problem with Sugino front chainring spacing, I'd love to unset this indexing, but I don't know how.
Solved it, it was the nut oriented incorrectly on the dura-ace downtube shifter.
Turning the inside nut so that its oriented correctly against the main tube, inside from the lever, and retightening the cable to remove all slack, and then setting limit screws again, I now have the shimano 105 derailleur with the Sugino  working correctly (non-indexed). Thanks for all your ideas.
