Thanks for the input! Before I leaned the low end, I didn't notice the rattle. However, the idle wasn't very steady. After leaning it out, suddenly the rattle appeared. I may be a tad too lean, as the acceleration is a little sluggish, in my ignorant opinion. When I ritchened it 2 or 3 degree's, the unsteady idle returned. My max RPM on an APC 22X10 is 6900 RPM, which I thought sounded about right. Could my high end be off enough to make the low end setting touchy?

Thanks Again!
