OutdoorKing Repair Forum Forums Repairs and Maintenance Questions on Trimmers and Brushcutters Two Stroke Trimmers & Brushcutters trimmer H needle set

hi bruce if i use a tach and close the H needle
to where it reads max rpm then open it 1/8 of a turn
is that the the way to do it or can i leave it at peak
when using a tach the trimmer im going to adjust is
a honda emt 20s straight shaft trimmer,

Tommy,
The reason that I say to people to back off 1/8 turn is so that will not run lean as this will damage the cylinder.

Regards,

Bruce
