Scamming is particularly rampant in South Florida for virtually everything.
There was definitely a HUGE difference on my second run last night- the 2nd cart felt like someone had put crisco on the back tires. I was struggling to keep the back in the back

. I think the tires might have been toast or something.
I just need to search around for an article or something on the proper line in a kart, and when to brake-throttle, because you clearly need a degree of throttle steering to make it through a corner with any momentum. Off throttle and you just pushpushpush, and on the throttle you are on the verge of swapping ends the whole time. Doesn't help that the total pedal travel is like 1 inch. Also, you have to throttle steer a bit to keep the rpms up so that you don't bog on the exit. Nothing was more frustrating than the exits where I either went through too slow, or over gassed it and went sideways too much, and then when I corrected lost all of my speed and you are back down near idle just like that! My brain can't stop processing this... I need data!
