180 main jets are a good start off for your stock engine IMO. try that w some 60 idles. that should run good. i had that on my 6port and it worked pretty good

Which is it a four port, 6 port, or built with the turbo houseings? as they all flow considerably different.......

are you in Ontario CALI?? if you are, bring it down to LA. I will mod that carb for ya. yes, depdning on what type of 13-B you have, 180 is a good starting point. But, I know your jets can go as high as 210 with 42 venturies. Play with the idle jet first. you can use up to 75. then main/air jets and the venturies.
