In his book 'Mean Business' Stephen Brunt writes a number of pages on McLarnin and he also described how McLarnin supposedly "battled jaundice that forced six and four month layoffs" (page 158 ) This is described as happening not too long after the fight with Jackie Fields, so if you can look at Jimmy's record and find any significant time being taken off by him between fights, you might have the reason. I would guess that it would fall close to the Snell and Farr fights.
Also, the L.A. Times on Oct 10th, 1926 describe how McLarnin was recovering from what the paper called a "severe cold" which put the fight with Snell back a little with a delay.
i.e. McLarnin may not have been at his healthy best for the Snell fight.
