Was given this blower, no history, looked hardly ever used. Fired up briefly with some fuel down the plughole but couldn't get it running so put it away - just seemed that bit too unused to drop at the tip.

Anyhows got it running today after a teardown which included taking out the Low and High mixture screws without the right tool, a Donald Trump of a job. In the process lost track of where they were set originally. Made slots in the screws with my Dremel to accept a flat screwdriver and have the upper rpm sorted but not the Low screw, won't idle nicely.

Advice on how many turns out for the High and Low screws please.
