[QUOTE="BigTerp, post: 331239, member: 9169"] Thanks for the thoughts!!! I forwarded this to my buddy to see what he thinks. I haven't checked to see if the carbs are opening up properly or if the timing advance arm is moving freely, but he may have. He's the engine guy not me :P . Actually it's the opposite of what your saying. When the pump is completely submerged the engine won't open up.
