My 2000 ski doo formula deluxe 600 has created a bog from half throttle to wide open. It starts and idles great but as soon as you pin the throttle it bogs down to the point where it will kill the motor. To me it seems as though it is not getting enough fuel. I have cleaned the carbs, exhaust valves and did a compression test with 120psi on both sides. Is it possible the fuel pump or filter is plugged up? I guess I am just looking for something I am overlooking. Any help would be great! Thanks
