Gentlemen,
I've been working on my carburetors, due to having too rich a mixture. Soot in tail pipe and sooty plugs. Corrected the float heights, and now can get blue in my colortune. However if I rev the engine, it goes to yellow. Everything I read seems to talk only at idle when setting via the colortune. So is this normal?

JIm,
Once you achieve the "bunsen blue" color at idle, SLOWLY increase engine speed up to 3000 rpm and the blue color should weaken, but not become more yellow than blue (if set correctly).
Another test is to bring the engine up from 1000 rpm up to 3000 rpm very rapidly and return. At this rate, it will go yellow, but should settle down to the original color once back to 1000 rpm for a few moments.. Don
Look sharply after your own thoughts. They come unlooked for, like the morning dove upon your window sill, and, if you turn to your usual task, disappear; and you shall never find that perception again; never, I say-but perhaps years, ages, and I know not what events and worlds my lie between you and its return.
