Default RE: hi.

LOOK IT UP is a great suggestion.
It probably does not have two low speed needles. If one of them is not an idle screw then it's a mid range needle and you DO NOT want to mess with that. Those are factory set and even the manufacturers say not to adjust it unless you are an extremely experence tuner and since you said it has two lsn's, I'm guessing you're not. I'm not trying to offend you, just trying to save you some trouble later.

Default RE: hi.

it could be a mix needle as well. the OS18TM has a lsn hsn and a mix needle just below the hsn.. so your best bet is to check the rossi site for there factroy settings and start there. you will need to completely retune your engine with the new carb.
