Hi all.
just a question on carb jet numbers.. I am running a 152 Main and 48 Pilot and looking to richen the main jet. does this mean i need to go to a higher number? so bigger number means bigger hole in jet which means more fuel? or is it visa versa? also what does the number on the needle signify? mine is running a R1172 Needle but FMF recommend running a R1173 Needle does this mean it will be a fatter needle to Lean it ?..... its all too much :-)
