I think my pedals are approx. 1" too far. As I look at the seat bracket, it appears to have a flange in place to center it. If so, my other option would be to shorten the boom. If I pull it back 1", will the derailleur take up the additional length of chain? Any more than 1" is unnecessary.
If there are other considerations, I would appreciate the advice.
Thanks,
Bruce

you have something like 6-inches of fore and aft seat adjustment, basic idea is to have the seat forward enough so the return pedal stroke gives you about 1/2-inch heel clearance from the frame. with the seat set up that way, if moving the boom all the way in still leaves the pedals out of comfortable reach then yes, no problem hack sawing off an inch or two of boom.
if your trike was set up properly, any movement of the boom will need addition or removal of links to keep it that way. see http://www.parktool.com/blog/repair-help/chain-length-sizing#article-section-4
