Stock settings for 990 carb?

[Chillin4life187]

Just switched over to a Walbro 990 carb. Can anyone give me the factory setting for the carb so i can set my high/low needle? Thanks

Basic Needle Settings: Low = 1 turn, High = 1-1/2 turns.

Mine runs sweet as on these settings. Just a basic G230 with Tuned pipe ?

We have 2 HPI 5B's, 2 Losi 5T's, & a Kraken Vetka5 all have 668 carbs & settings are 1 1/4 L & 1 1/2 H but I just finished a built on a Losi 5B with OBR motor, there engines come with a 990 carb & they state that a 990 carb settings is 1 1/8 on low & 1 5/8 on high needles. This is my first 990 carb so I will use there settings to start with. Have to wait for better weather to break in & run but In this video they discuss all 3 common carbs. I got some good information from it about tuning. http://www.oneillbrothers.com/blog/breakin/
