race settings are usually around 3.75 turns on low speed , 3.5 turns out on high speed , 1turn out from just closed on idle screw .

any Q's just let me know

are the needle settings the same for the n21r and n21r-bf engine's? my lsn was too lean...3.5 turns out. guess i didnt go rich enough. i'll try these settings.

U r correct

The only thing is you don't really need the compact header for the mugen truck but it is kind of a must for the buggy .

I have been preferring the 2084ss over the 9853ss for overall runtime/power . The 9853ss def. Makes more power though

Hi Monty,
I need your help. I am confused on the correct HSN setting for my Plus-21C. If you go to the Novarossi web site and watch the video clip of Adam Drake on tuning he states that a good starting point for a “race tune” for the HSN on the Plus 21 is “flush to a 1/4 to ˝ turn in. If you use the “factory setting “ of 3.5 turns out as a base line, it is a long way from flush! Is a “race tune” that far from the “factory setting” of 3.5? Every time I try to lean out the HSN that much, the temps shoot up. I have never gotten close to a HSN of flush. Granted, the engine is still fairly new. Maybe close to 2 gallons at the most. There is still a slight mechanical pinch. I use Byron’s 25%, O’Donnell T98 plug, and a 6.5 card insert. You thoughts would be appreciated! Maybe I am just over analyzing things!

factory settings and race settings are nothing close to each other

a good starting point if you get the carb out of whack with most pipe combos is 4.25 on lsn and 3.5 on hsn , approx. 1 full turn open from just closed on the idle gap . for the plus 4 engine and long needle carb
