31k carb needle jet size

[alankelly]

Hi all

Sorry for all the questions but many thanks to all and their advice

Just rebuilding my 31k carbs for my 350lc 4l0 rebuild and have decided to replace all jets etc as the carbs I have were sourced from elsewhere (as the originals were in bad shape) have been fitted with a mixture of jet sizes and needle sizes etc

Ie one main was a 120 and the other a 220☹️

So my question is please as I am replacing all the jets with new to ensure the carbs are in the best shape possible what size please should the needle jet emulsion tube be for a standard ypvs 31k be please as I have one with a 345 p-2 and the other with a 345 p-0 and as I am replacing the needles with the standard ypvs 5k1 what is the matching needle jet size please I need to fit

As just for reference this will be my final set up as a starting point

Pilot 27.5
Main jet 240
Float valve 2.8
Needle 5k1
Needle jet TBA

Any help much appreciated

Thank in advance to all Al

Hi Alan
Pretty sure you need 345 P.0. Hopefully someone will confirm.
