Carb Tuning with IR thermometer?

[Stanley]

And one does not simply tune SU's, I guess. Easy enough if you just want driveability, but it's taken me some doing, to get max performance without fouling the plugs.

Using the IR did help me. Took the dead IR back to H.F. and they gave me a new one. Took a bunch of measurements and saw the front end (closer to the fan) was consistantly running hotter on both sides. Reset the mix, advance the distributor a little and took a ride. It's revving much better now (but I still think it's on the lean side, even at 3 1/4 turns down, the mileage is too good).

Way cheaper than a WB or EGT's. Won't give a quick exact answer, but what would? It might help to take a lot of measurements and graph the results. Also thinking about putting a fuel pressure gauge. The Ztherapy video says F.P. affects the mix - more F.P. =richer. Makes sense to me. So many variables in a simple system. Drive, adjust, repeat is also the only thing that works for me in setting the timing.

Lazeum, my Dad says the same thing, word for word.
