Frag I raised a similar question back along about the differences between using the comer wheels (which I now do religiously) and the jet rims and although the concensus was that the different wheels would make a difference, which I agree with, nobody would give me any idea of how much time you could expect to gain/lose in wheels. I don't think it's really worth pursuing time in wheels when you have a novice driver who is 3 seconds off the front because imho it would be near impossible to attribute any minor gain to the wheels on account of the natural development of the driver. If he suddenly goes a second quicker because a penny has dropped about a certain bit of track and he realises he can go quicker, he will still be 2 seconds off the pace and the parent could incorrectly conclude that the time was in the wheels. My lad can come in after a session with all 3 fastest laps on the mychron within half a tenth of each other and more often than not on consecutive laps, which is useful, but the track can easily go faster or slower and I've come away from a test session many times wondering if the tenth gained/lost was the track or the change made between sessions. I resolved to using the comer wheels so I have that control in place to make testing easier. When he's within 3 or 4 tenths of the front I'll start trying different combinations of wheels. Incidentally I wanted to say thanks for the help on the carb. Last weekend I went to clay and set one carb by trial and error and having got it right, I set the other 2 and the performance was identical. I concluded that it was my fault for not using fresh neat fuel at the start of the day.
