Possible problems

- carbs aren't sync'd

- clogged pilots

- needle clip in different positions on each carb/came out all together (unlikely)

- Choke tube fell off

- cracked reeds

I own the quad hes talking about i took the carbs apart to check the jetting running 290 mains 27.5 pilot dont appear to be clogged. Is this proper jetting for the whats done to the motor riding at about sea level to like 1500+ in about 10-15 degree celsius. Reeds are not cracked havent checked the clip yet i will tomorow. Did a compression test on the motor too both have about 150psi which i belive is pretty good. Any help would be apreciated

sync the carbs. do a search on here about it and if that dont work unhook the tors

TORS is removed and the carbs are synced. I have the carbs apart right now but tomorow im gunna put it all back together and see if it made any difference if it is the same id like to see if swaping the reeds to the other side will make a difference are both reeds the same can i just swap them over they look the same to me.

yeah both are the same you can swap them over. make sure you slide are going up and down allthe way at the same time. its a carb issue. forsure. how did you sync them?

[180sx Fan]

i syncd them with the sights on the carb and visually looking thru the intake. Does anyone know if my jetting is correct though? Good to hear that someone else thinks its a carb problem and its not just me.
