Thanks buddy,

I hate it that you had to right all that out on my behalf but I appreciate it all the same. I understand the tolerances and why they have to be so perfect. I used to race 2 strokes and have done my share of rings and/or complete rebuilds in the garage, usually twice a season. I can usually get what I think is a good tune on 1 needle or the other but believe I may run a lean top that disguises a rich bottom or vice versa. It's that balance for the sweet spot that evades me. I think I just need more time to develop a better "ear" for this. I can get decent run times and steady temps also but my engines still don't sound like the pro's at the tracks I go to but I can be patient and work up to that. Thanks again for your time and I apologize for the lengthy nonsense, I'm just a talker I guess...
