[QUOTE="DaveRS575, post: 555026, member: 34015"] Hey Gary, I did not check the crank bearing per se, We did give the piston a thorough check for any wobble, and full motion however and it was all good, no side to side movement whatsoever, and smooth flow of movement when turned over, no friction, grinding, or difficulty, so I made fair judgement that it was all ok. The top of the piston was covered with burned on black fuel, indicating to me that the guy who was running this before me (or me I for that matter) May have been running a richer mix than necessary. I go around 40:1 with the Amsoil Pre mix. I don't recall anyone recommending I run amsoil at 80:1 though?? (previous post by TVRIDER) That would be a mighty lean mix I'd think... right? The cylinder was very clean, very very minimal scoring, and the top of the piston, once cleaned of all carbonized fuel/oil mix, was smooth and new looking. It was pretty well crudded up though. The valves were a bit tacky too, but once the gears and everything were cleaned thoroughly, they timed in nicely, and rolled smoothly open and closed. The gears all looked "good" taking slight wear, but fine good for at least one more season I'd say. I did not get a chance this weekend to get her really heated up, but hopefully very soon, so I can tell you if the noise is gone or still there. I can't wait! :aj: [/QUOTE]
