When i set the lsn a bit rich, it will just flame out aft idling for 10secs when i punch the throttle. When i set it a bit lean, eng will kept on reviving at high rpm n when i tune down the lsn.. Punch full throttle aft 10sec and eng will flame out..
The only way i can keep the engine running is to keep the idling high..
It cant be the tank or the fuel lines as it works fine with my xzb. Btw, im using a dyn053 pipe. Hsn is 3 turns out, lsn is 4turn out and idle is slightly more then a turn out from close without the 7mm venturi.
Thanks
