Advance/retard control

[Patrick L.]

' It wants to find the sweet spot ' ? All by itself ?

1/2 to 3/4 down is the normal position. These monsters really don't need 40º of advance. Full advance may be OK for continued highway speeds. I never [ well, very seldom ] bring the lever fully down. Just set where 'it' likes it.

Over the years the ' mechanism' wears and the lever doesn't want to stay put. Many are like that. This can be fixed but requires some work.
