No, I haven’t been able to get out lately. This weekend or next hopefully.
I can’t get something off my mind and maybe if I mention it here, there is an easy explanation. The kart came with a dellorto carb with a straight intake. In the box of misc parts, I find a spare dellorto and an angled intake that has a larger boot (it fits the pwk 38). Then on the spare engine is another angled intake and notation on both by that it was modified by Super-Dyne (same on the engine). So, if you’re keeping count, I have 2-38mm intakes, 2-30mm dellorto carbs and 1-30 mm intake.
So my thought is that someone kept whatever carbs were being used for this setup and threw in the 2 dellortos. I don’t think it is normal to use a pwk for a k9b, so what other ~38 mm carb would have been optimal for a modified k9b?
