Any ideas? The A/C bogs it down and it gradually slows down until it dies while idling.

Too much freeon in the system or the pump is getting ready to lock up..??..

Interesting thought. I hadn't considered a problem with the A/C. The pump is hotrodded and I think the idle was just set too low. I bumped it up and now it's fine. I might have it a little high, see any problem with that? The manual says 780 RPM with AC on so that's about what I did, but now it runs just under 1k with the AC off.
