Hey everyone! I recently acquired a 95 XP 720. Did a full rebuild on the engine and carburetors due to it sitting exposed for a long time. Got it running but am struggling to get it to Rev smoothly through the rpm range.

It'll start and idle fine, but as soon as I give it throttle it'll bog down and die. I can blip it through and get it to Rev past that but then it'll Rev up to about 7500 and stay there for a long time. It doesn't want to idle back down.

I currently have the pop off set to about 30psi, low speed screw set to 1 3/4. High speed at 0. I don't know which jets I have or needle valve size. I assume stock but don't know how to measure it. It also came with a K&N air filter on it.

Any help would be greatly appreciated.
