Hi, 
Swapping engines and need to match crank shaft size to mount Pullys on new engine and canno  find any info on actual size of Tecumsch shaft , Predator : shaft is 00.75"*2.43" keyway is 3/16" and end tapped 5/16-24UNF ? 
First time working on engines so really not sure of best plan to swap, or can i get new Pullys for the new engine ?
