[b]GN:

If you can't go rich with the HS needle your pump pressure is definitely too low. Crank it up until you can go rich on the HS,

This may make your mid range rich again, out up with it, it's cheaper than ruining the engine with a lean run, but there should be a place with good mid range and enough fuel at full throttle.

I said earlier about two turns out on the HS, if it works out to 4 1/2 turns to get the mid range right and get the HS a little rich that's still OK.

It does sound like you're getting there.
