On the glow site there is a post on the new OS 35AX appears to be a real grunter not a speed demon and turns a 12x6 at 9200 on glow fuel. Looks good and in a 25 size case ( same mount as the 25 or 32 SX)
as a diesel conversion this would cover 25 thru about 45, front carb. It is the replacement for the 32SX. I have already called Davis on this one. Looks like it would be an equal to the irvine 40 diesel in a smaller package and about 4 oz lighter at 13 oz with the muffler martin
