      Jim – He just points at it…lol.  When TJ was younger and I wanted him to do more on-track carb adjustment, he would always say that he was, but I knew he was afraid to, so he would “pretend” to turn the needles, or just point at them.   I’ll leave it to him to explain what he does now. :)

      Ok, driving a Mike Wilson w/ Leopard, RR. Rear bar, full stiff, frt bar in, scales good, 90mm rear hubs, medium axle, 54 1/2 rear width. The car turns in great, through middle of the corner great, exiting corner and back on the gas, I get a push. At the point that I feel like I should be straightening up the wheel, I’m still giving it a little more turn. I’m guessing that I need to soften the rear? As in, the rear is lifting just fine, but setting dn too quickly, giving me an exit push? Maybe loosen 3rd bearing, maybe shorter hubs? Am I on the right track here??

      Sorry, I missed this topic!

      Jim, I barely touch the low-speed. I start at around 1-H and 2-L and lean in from there on the high-speed to get to my desired EGT. Usually end up around 7/8. If I feel like I’m good on my high-speed after leaning it in, but I need more mid-range, I might try fattening the low-speed up. Sometimes it seems like if you go leaner on the high, you start to get a hesitation in the mid-range and usually fattening up the low cures it.

      Mainly we shoot for 1050 or so EGT. Somewhere around 7/8-H and 1 7/8-L seems to work well.

      Ric,

      Take your rear bar out. You should never run that. The kart is probably struggling to keep lift through the corner because the rear bar is keeping it flat. I bet that cures all your issues.
