amature engine tuner
 

im new to niro but not to rc cars would love to know factory setting on my old rx 21 race nova rossi carb that is also on a hyper 21 pro 8 port tuning is real annoying very keen to learn :nod:

Here is how I have always done it, well first it depends on how many needles you have, if only 2 back them both out until they are flush with their housing, then turn them in 1 1/2 turns, that is going to be extremely rich, it is a safe pace to start with on any engine, if you have 3 needles, don't adjust the 1 on the carb slide where the servo connects, until the other 2 are tuned properly, remember richer is better, keeps the engine cooler.

check that the low end needle only a 1/2 turn sorry wasn't thinking
