George I know this is an old thread but why did u use a jackshaft on this machine. I'm building an mtd chassis for a local club and am using the 420cc predator clone. I wasn't going to use a jackshaft but am I missing something???

Not George,     Shortens the chains and also gives your more gear ratios to play with.    Most run 35 chain to jack shaft and 40 chain back to axle.   Biggest thing is to keep the chains short.  They live longer .

Trying to get the ratio without a jack shaft is very hard.  And as above chain length.
