Try turning both screws all the way in - not tight, just a little less than snug, then turning them each out 1 1/2 turn. While you're right there, wiggle the throttle shaft - that which the throttle linkage attaches to - runs vertically through the carb. If it feels sloppy side to side you're sucking extra air, there. Whole new subject, I know.
The fresh charged battery makes a big difference, doesn't it?!!!
I'm going to Buxton this weekend to pick up a 1811w/450 snowblower. 6 hours, one way, or I'd look you up! Getting an engine going over the internet is like trying to tell someone how to whistle by mail! Frank
