Engine is back from a very reputable builder, and I'm trying to adjust the clutch, but I can't get enough pull to engage it at all. Even with the adjuster screw all the way in and the cable screw all the way out, I get a little action. Seems to me it may be missing ball? Looks like the parts diagram shows two, one in the clutch basket (Right side of Eng) and another of the left side? Don't seem to have one of those and I'm not sure where that one would go. The Push Rod protrudes 1.75 from the case. Is it possible to Right side ball got got lost or potentially never installed? Can I push one in from the left side ? Thanks in advance...
