Are you talking about the idle screw itself or are you looking down the barrel of the carb and adjusting it (which is how it should be done)?

Dont necessarily worry about the factory needle settings and trying to get them there, they are very general. If you can get it to fire your in good shape. Get it to start and warm up a little, make sure the throttle trim on your radio is zeroed out before starting it. Once you get it warmed up, then try lowering the idle screw and see where the idle goes from there. If you cant get it to lower than you'll need to richen the low speed needle some. When you get it running, you really dont want the engine racing and clearing out, you want to see oil coming from the exhaust pipe and sluggish performance, but you also want to see temps in the 200 degree range.

Your low speed needle directly effects the engines idle, if you richen it, it will get lower (and load up eventually), if you lean it, the idle will get higher and take longer before it loads up and stalls.


As far as the topic, think about how much you want to spend and then consider your options. Theres a lot of good engines out there right now in the price range of the Vspec .21 and .28. I just bought a ninja .28 myself and hope to break it in tomorrow, but I have heard from a few people that own them and 10 minute+ runtimes are possible with this engine.

Where do you race in CT? I usually run at wolcott or madness, at wolcott a .28 can be utilized for sure with all the bigger jumps and stuff, madness is a little tight but a lot of guys still run .28's there.
