My 66 302w 600cfm holly 1850-2 is running rich. I'm not too experienced with carbs, I'm largely going off youtube videos. I have replaced the needles and pulled the primary bowl as I was going to replace the jets (size 66 factory standard, had a pair of 64s to lean down) and it had 62s in it. Not wanting to make it richer with 64/66s, it must be something else... not sure what the best path is to take now....
Can anyone recommend someone SE suburbs melbourne who can tune it?
