Just got a Dynamite balancer from Ebay. The guy said it was new never used and it was! I know why he never used it, you put the tire on it and spin it and it just stops any where, different spot every time. I fixed it, I took the rubber seals off the bearings, now it works right, heavy spot down every time.
Just a FYI for anybody using this balancer. Oh, and spray some lube on the bearings before using too!♠
