Uncle Charlie, hoping is hoping, although don't put forth too much effort into absorbing information I post that you learned, knew and forgotten long ago! Oh by the way, is that osmosis relative to cosmos?

..so why not test it yourself on your combo? What works on one might not so much on another.

A friend and me were talkin and seems it would be a waste of time to Dyno a engine in 95* weather and very high humidity. because you will have to completely change the tune when the weather is normal. Seems it would be better to wait until the heat/humidity drops a bit.jmo Smile

I did this very thing Sat. night, I made my first pass without the air pan, shifted at 6200, ran 6.134, next pass put pan on car, same shift point, 6.101, next pass, moved shift point to 6500, went 6.088, then elimanations started, I dialed 6.08, went 6.085, left same dial on, went 6.082, next pass, dialed 6.07, went 6.081, left 6.07 on window, went 6.080, that was the end, had a -.005 light, but was a good test and tune night, temp was about 88, humidy was about 70%, barometric pressure was around 29.25, end of story. cheers

342g on July 6th 2010, 4:52 pm

Carbs fine, I just need someone to help me with the jetting, and air jets, I believe there is more to be had, if I can figure it out.

You need to know the "lean/rich" fuel ratio throughout the run, otherwise you are just shooting in the dark.
You'll get there but, it'll take 10 times longer; maybe 20 times longer.
