well it appears my front bearings seals are shot. She's leaking fuel like a fawcet..Unfortunately this bearing is a aftermarket ceramic bearing....I wont say what manufacturer till they have a chance to fix the issue... My original issue was a hanging throttle slide, it mimicked an airleak, so i replaced the front bearing ... I also fixed my sticking carb, but my new bearing must have been leaking right off the bat.......Anyways I re-installed the facotry bearing and the motor is running like a champ..... Extremely powerful for a .21, i am very happy with the P7's power...
