Wade, I've been called a lot of things in my life but never a bomb, although I do have a 750 pounder setting in my basement.. :usa:

Wade,

I ran the that exact same set up last year at the HOF ride and was very rich! We raised the "E" clips on the needle jets to the top groove to lean it out. It helped but didn't cure my too rich condition. I plan on dropping one main jet size to 250 PTO and 240 Mag.

Hope this helps.

Wade,

Keep in mind that those carbs came off a reed valve engine. The 340/S is piston ported so the jetting will be different.
