So my grubee skyhawk gt5 is having some issues. I have just bought a new CNS genB carburator and whenever I have the choke all the way down I can only give it about 1/3 throttle without it dying. Then if I have the choke on I can give it all of the throttle but when I let go of the throttle the engine dies. I have adjusted the two adjuster screws a whole bunch and I cannot figure out a combination that works. If you have any advice, I would greatly appreciate it. Thank you. Oh I am also running it with a boost bottle.
