got a 406 with a cast steel crank--came in my old blue 25 lm--when I pulled it there was the crank counter weight (small flat plate goes between the fly wheel & crank flange) odd thing is it had a standard balancer on the front--looking at the crank it has some weight on the front throw---is it possible to balance half the crank??? TEASAR in MINN built it----looks to me like it was balanced to use the plate on the rear and a standard balancer on the front
