WT-990 Carb Needle settings

[Rampagemt2016]

Good starting point on 990 carb is 1 1/8 on low needle and 1 5/8 on the high needle and tune from there. I leaned the hi needle just a pinch and the low needle was fine

Don't lean out your low needle any more richer the low needle

I usually end up around 7/8 on the low and 1 1/8 on the high.
