Hi Dave,
In continuation to the cleaning of the regulator and plunger of my YS 45 FS.
I went out to the field to reset the regulator - I found that the idle finally settled when the regulator is approx. 0.7mm out of the regulator body which is also about one whole turn ( out - counter clock wise ) from the previous position. The transition from idle to max is fine. Do you think I should reopen the reg. to check that all is fine or to leave it as is.

Thanks again for the patience and answers
Brian
