My WS7 is giving me some problems. I've been chasing a tune all week in preparation for tomorrow. I've been running it for a tank, letting it cool, then running it again. It seems inconsistent from tank to tank. I've been getting a lot of stalling in the higher RPM range while accelerating. The engine seems to get hotter and hotter during each tank until it's about 250 or even 260. After a few minutes, there's plenty of smoke, but the first few minutes are often much less smokey. I'm thinking my bottom is too rich and my top is too lean, but it's hard to detect because my idle is too high. I'm hoping I can get it set right before tomorrow.

Any suggestions on where I should be going with my needles?
