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.

ok there's this little something called a manual that comes with your engine. READ IT!!!! It'll tell you the settings you should use to get up and running and then you can experiment from there.

Well I have the novarossi N21BF and the owners manual says to leave the needles set at the factory for break in but doesn't actually give you the turns. My suggestion to him is to contact novarossi.

Rippin it up!!

Yah the manual doesnt say where to put the needle for breakpin. I contacted Novarossi, and are they good at answereing qustions and sending them back?

Istill havent gotten an e-mail back
