And I wonder why i hard time setting the timing...

You realize that the first link you post is an SFI unit for an externally balanced 360 and the second link you posted is an SFI internally balanced unit. Maybe that was the whole problem.


NO..that was not the problem...as said..they both use a bolt on weight ..so the balancer can go both ways...

beside the weight does not bolt on to the outer ring which is what slipped....it bolts onto the hub of the balancer..
