3x3 mod with JD needle size advice needed: Red Pill or Blue Pill?

OK, I'm half way through the 3x3 mod here and not sure what to use from the JD kit, red needle or blue needle and at what position.

Gulf coast Texas here, 14ft elevation, high humidity, high heat most of year

I'm leaning towards 155 main and 22.5 pilot (Extended Fuel Mixture Screw). But am open to advice on this as well.

Thanks!

i think red is leaner and usually needs to be one clip richer than blue needle

Hey thanks again.

Is there any other info I might need? Like can you recommend how many turns you would turn the extended fuel screw, or anything else like that you could advise on?

2.75 is a good starting point ,you may have to adjust it a little...Just use this procedure to fine tune...
