Correct Needle Jet For 78 Cr390

Hi all,
1st post, having recently (finally!) purchased my 1st Husky. Trying to clean up the jetting by getting back to stock settings and go from there. Previous owner tells me the needle jet is not the stocker-haven't pulled the carb yet to verify. Anyway, the parts diagram refers to the stock needle as Q-8 but scanning through Jets Are Us for the 38 Mikuni I don't recognize any of the numbers. A little help would be much appreciated!

Thanks,

Brian

This page from the Sudco catalog (p. 212) will provide an explanation of Needle Jets, Series, and Type Carb Application:

That was a big help, thank you.
