Hi All,
Been working on carbs my whole life but am now only really starting to undersand the many functions of each hole.
It would be nice if someone could do a stickie with the definitions of all the terms used on this board. I understand IFR and MAB, but some of the others have me confused.
I will be working on my first set of 4224's for a tunnelram set up and want to learn the ins and outs.
Thanks in advance!
Matt
