Brand new here. I just got into RC a couple months ago after picking up my buddies Inferno MP777 (i'm almost positive it's a 777) and a Revo. Loving it!

The Kyosho has a Novarossi Rex engine on it with a Rex carb. The carb has the 3rd needle and I think that's why I've yet to dial it in properly. I found a nice little PDF on it and it was some help but I just don't know where to start.
It runs good but lacks in the low end. Doesn't "snap" after comming out of a tight turn.
What kind of turns should the 2nd LSN have in realtion the 1st LSP.

*had an issue with the arm comming off the piston the other day. Luckily got it back together without any knowledge of how to. Are replacement piston & sleeve's available anywhere for this engine?
