well, no 2 carbs will be jetted the same as in "what jet should i use?"
the best thing to do really is to get a variety of jets and try each one in progession until i runs good.
what works for one, may not work for another.
start with a low jet # (like 68 for example). get the engine warm and ride it through the entire throttle range, low speed,. mid speed and top speed.
if it bogs down at w.o.t., chances are, that jet is too lean. also check the plug color.
then work your way up in jet sizes, one jet at a time until it runs perfect through the entire rpm range, and your plug is a nice tan color.
it can take a few hours, or it can take 5 minutes in some cases.
the air temp, humidity where you live and your elevation also come into play.
here's what i did (which may not work for you).
I removed the stock nt jet, and had no idea what size it was...assumed it was a 70.
I stuck a 68 in, and rode it.
the 68 was way too lean. so i jumped up to a 72. it ran a lot better. then i went to a 74 and that was a bit too rich, so i dropped back down to the 72.
there have been a lot of people who say that the stock (presumably 70) jet is too rich and they end up leaning it out with a smaller jet.
well, i had to do the opposite and richen mine up with a 72 (assuming that the stock jet was a 70). my ran like it was jetted too lean with the stock jet.
it's a trial and error thing, and remember to keep your stock jet set aside from other jets because you can always throw it back in and start over of you get confused.
if you buy aftermarket jets, normally they are marked with their sizes, but the stock nt jet will not be marked with it's size.
