howdy, i have a 302 ive been building for awhile. pretty much typical, mild cam, alum heads, headers, performer rpm intake 650 edelbrock carb, when it first starts, (cold) it idles kinda high, (1,000-1,200) then once it gets around 190 it drops down to 4-500 and barely wants to stay there, should i adjust the timing, or fuel? while its warm or cold?

you need to adjust hot idle screw on the throttle linkage, then when cold set the screw on the throttle step up for the choke and set choke properly.adjust
