Thanks for the link Ron. Those K&O are some pricey devils. See them on ebay in the $300 range and up. Mine is a flex shaft in there the two halfs split below the engine. Im thinking there is a half crank with a hole that ingages into the engine crank then you slide the motor through the first half the bottom end. Then there must be a collet with 2 grub screws to hold it together. Its hard to picture without photo's . I will load some later if I can get a chance.
