Jack, I don't know if you have more that one carburetor. It helps to have
at least one EGR per carb. Ideal for one EGR per cylinder. Leaner
mixture=higher EGR temp and more power. One method is to keep leaning down
until you obtain the highest temp, then back off one jet size, (to keep
your pistons from meltdown). On my tiny 850 Honda, with twim DCOE's, I like
to see 1200-1300 temp. Wnen I'm not overcome by the usual red mist, I check
EGR on the longest straight.
