Jetting questions

[Fordtrax]

ok i finally got my FMF Gold series pipe on and man is it cool lookin!
Took my carb off and found it to have a 155 main jet so what jet would any of you guys reccomend? im thinking a 160 jet would suffice help i dont want to burn it up!

perform a plug chop on it. ;)

Ok im a dummy but what the heck is a plug chop? I know how to read plugs?

adjust the jetting untill you get the desired plug color at WOT.

yeah i just went and picked up a 158 and 160 main jet and will just pop the 158 in for now !
The place where i went said sometimes you dont even need to jet it or it might need to be leaned too?
But i dont have any faith in that place and i just stuck the 158 in and will go and do the Kehin website thing that 86 r hooked me up with !
