I have a Novarossi Rex R21b engine in my Hyper 7 PCR RTR, and i dont know what the break-in setting should be for the LSN. I set the MSn and the HSN, just like i always do (high speed needle 2.5 turns out, MSN very slightly in from flush with carb) but the LSn is the one im having the problems with. The way i set the LSN on my other engine was 2 turns out form flush, but with this carb once it wont go past the flush mark. I keep on screwing and it doesnt do anything, so i obviously need to set this differently. what should i set it to?? Ive already turned it becuase the engine wouldnt start, so dont tell me that it comes ready to break-in.
