[QUOTE="cthowards, post: 1140691, member: 67091"] I will check the valves but I am hopeful they are in spec (only 1.9 hours on new Kibblewhite vales and springs, etc. - a local shop installed the valves and handled any lapping, etc. and set the clearances). In connection with the rebuild, I installed a Ride Engineering fuel screw and it feels looser in general than the stock and it also vibrates out so I have it wired in place. I learned from prior threads that I searched that the spring should be stretched out to keep tension on the screw. In any event, I will definetly go 1 up on the pilot as I am near the end of the current adjustment (2.5 turns out which is very close to the max of 3 turns) and will also consider going up on the main. While I'm at it, I check that o-ring and spring. I may even put the stock fuel screw back in...just feels much better. Do you think any damage was done to the motor (piston/rings)? I didn't see any flakes of metal on the plug even though it was very white. Thanks for your replies. [/QUOTE]
