I should have mentioned in my previous response, I bought Tom's electronic ignition and am very happy with it. I've spoken to him a few times on the phone. Like a lot of guys his (and my age) he has very strong opinions about carburetion and proper setup. I happen to disagree with some of what he says, but my decision not to go with his setup was based upon the look that I was going for and not any dissatisfaction with him or his products.
Like Dave says, the guy is retired, so his responses will sometimes be delayed. If you don't know that up front, your expectations might be incorrect.
