Been having problems getting my new set up dialed in just right. Here's what I've got: Newly built 302, mild cam, 4 bbl quickfuel HR 580, c-4, 3.50 gears. Here's how I'm set right now: 6º advance, idle adjustment screws are less than 3/4 of a turn out, float level right on the middle line in the windows. Like this i get really good power all around but when pulling out I have to go easy on the throttle or I loose power and get a small backfire. I'm also only getting 6-7 mpg and it still smells like it's running rich. If I turn out the idle mix screws any further, It get's rough. If I go in, it starves. I've tried advancing through the range up to 12º but the further up I go, the smoother on the hgwy but no power down low. Not sure what to do next. Jetting that came in it is 66 for primary and 72 for secondary. Never messed with jets before... Do I need to go down a size?
