Setting up my OS 61?????
 

I bought an OS 61 (used) and I've followed the insturctions up and down on setting up the carb.

But I still seem to be having trouble (sluggish, and rough running sound).

I have the low needle set to about 1 & 1/4 turns.

The mid needle set to about 1 turn.

And the High needle set to about 1 turn.

I was just wondering your PREFERENCE settings, and how you go about setting the carb for MAXIMUM preformance.

Yours,
