We must be getting good at tuning down here in NZ Shane
our 3 needle GXII motors are going well and took yet another win yesterday
i agree theres no need to mod the GXII , its a ball tearer out of the box.
and just to clarify with the 3 needle carb. i wanted to ,make it clear that its not a bad carb. the decision to keep my range of engines 2 needle was based on their great performance and ease of operation. something thats very important in the nitro game.
the MG66 carb is the carb we used with adam alexander in Pattaya when we won truggy at Nitro Party 2009. if it can do that on that track against some of the best then i say its a good carb. Tuned it in under a minute just before we set out for the final and it didnt miss a beat.
so my opinion is based on a bit of my experience on using it.
Just an FYI Adams wife was his pit crew for the first few days of racing quals and she managed to get it pretty spot on. So props to her for her support.
Now as long as people know what the MSN does then youre fine. just mark it when its set right so when it shifts, and in my experience MSN needles can shift, just rurn it back.
