OK any one have an experience with the .18 os cv-rx slide carb ? heres my issue > freshly installed .18 in my rs4 2nd gen with 2 speed . broke in under heat cycle method topped at 208 within 4 - 5 mins shut down >bdc >after run oil in head button hole cranked 5 times> cool then repeat went through five tanks of odonnel 20 % about 2 months old . Ran fine through the break in LSN was 1.75 turns in from flush and hsn was 2.5 turns out from lightly closed .went through two os 8's for break in one was NIP one was used but still good >>>>> NOW when it fires up it runs fine starting to tune 8th turn at a time getting good speed out of it but when i get to half tank it wants to sputter and choke out at full throttle ????? I dont THINK the carb is opening up too far it idles fine and is steady at 200 to 210 .. I'm lost have any ideas please help . I have a Brand new plug the tank is sealed at the lid and im pretty sure im getting enough back pressure from the exhaust .
Any thoughts or ideas would be appreciated .
thank you all

it sounds to me like a lean HSN, richen it up a little bit. wait some other replies too because i am not 100% sure.

Thanks I did try richining it up and it still seems to choke out a bit as soon as I top off the tank it runs fine through the whole throttle band .
