I have a 2001 xcf 440 sp edge I bought this summer. I thought I had it ready to go. It starts a little hard. Ideals fine runs fine when cold. It only tops out about 45 mph. Seams like it want to go faster but just can’t get there. Once it warms up it just bogs down and will not even move the sled. I have to play with the gas and once in a while I can get it going and will run in the power band for a little bit and then bogs again and will not move again. I have cleaned the carbs, new gas lines, clean the fuel screen. The main jet is 340 on both carbs. The air control is set at one turn. Ideals at 1800. Could not see the numbers on the other jet. Spark plugs are brown. Not sure where to go from here.
