2 Needle Carbs!

[Shaun]

I Just Received The Xtm 457 Engine And It Looks Awsome, However I'm Just Curious Are The Carbs That Only Have 2 Needles All That Much Different as far as tuning then the carbs with 3 needles besides the obvious fact of only having two needles

Easier to tune.maybe not as precise at tuning but easier. The three needle carbs are great for getting that fine edge over the competition If you are good at tuning them.

2 needles are better then 3 IMO ... one less thing to go wrong and have mess with

Is that engine made by the same people who make the LRP Z.28R spec 3? They look identical and have the same specs.
