I've read that to adjust the carb that the needle should be screwed in until the engine falters, then out until it faulters, and be left in the midpoint.

That's where mine was set to, but it slowed down under a load, sputtered and sometimes stalled.  Do I want to be setting it slightly richer or leaner from the midpoint to overcome this problem?  The needles midpoint is 1 5/8 turns out from a gentle bottoming.

Is there something else I should be looking at?  I know I can trial and error on this adjustment, but during a storm would rather not be messing with it.

Thanks!
