Wellll, Im jetted with a rt dax carb at a #70. i should be theoretically at a 68. so its running a tad rich. but when i put 32:1 in it, my already fowled plug comes out with a white tinge on it, as if it is running too lean. Still need to try and put that third hole in for better fuel atomization. i d k. its been hard to tune perfectly. and right after I had the nt carb running perfectly choco brown XD
