Jim, I am not saying that they would or even could do what you and all of the folks you mentioned do. And that it isn't great for the sport that you all go above and beyond to help us racers out. I agree with your statement, and I, as well as most guys here, are very thankful for what you all do.
I order parts from and services many folks here on Bob's and try to spread it evenly, I do it because of just what you said, to support those who help. However, it's extremely frustrating when you unexpectedly need a common part (especially when you are a new race dad and mistakenly don't have a spare that experienced folks would keep on hand) that would generally be in stock on Friday afternoon for a race on Saturday afternoon and don't want to spend $70 overnight shipping for a $30 part. When you can run to a B&S dealer who might stock common items since they are in close proximity to a kart track and get it quickly. It's pretty humbling to tell a little boy who's excited and looking forward to racing tomorrow that he can't because dad didn't know to keep a spare part on hand and watch him try to hide his tears.
Again, please do not think I am trying to be an **s or that I do not respect the ability or am not appreciative of what many of you guys do to help, that was not my intent at all.
