well i change the prop hub and prop shaft on the 56 to a DLE55 hub and it bolted rite on with out having to change the timming,how is that for a clone engine.also clean the surface of the reed block up a little with 220 wet or dry paper to get rid of some of the rough casting.
i have four gals. through it now and is getting 200 more rpm's than the dle55 i have.
