I noticed Rocky Mountain is carrying the Dial A Jet now for the DS and was wondering if anyone can give any Pro's or Con's on it.

 

I was thinking of getting one after I jet my carb and get it running right.
It seems pretty good for elevation/weather changes.
Anyone actually used one?

 

Just Curious,

Somebody explain the "Dial a Jet" to me please.(thanks)

Air enters the Dial-A-Jet body through one of the five pre-selected air correction circuits in the rotary dial. Each of the five air correction circuits is a different size allowing either more or less air to enter the mixing chamber. More air would be leaner (larger hole) and less air would be richer (smaller hole). Fuel from the float bowl is instantly drawn into the mixing chamber and swirled with air at a high rate of speed emulsifying the fuel. The fuel mixture is like millions of tiny thick skinned balloons with air inside. This is called an emulsified fuel charge. The emulsified fuel charge is inducted into the carburetor through the secondary main jets located in the fuel delivery tube. At this point the Dial-A-Jet is way ahead of the rest of your carburetor. All of the other circuits in your carburetor introduce raw liquid fuel into the air stream, just beginning the atomization process. The lightweight fuel mixture from the Dial-A-Jet only weighs 10% of what liquid fuel weighs. Slight changes in engine load can be quickly and accurately compensated for with this lightweight fuel mixture.

That appears to be the jist of it.

$70 I believe I will be getting one I just spent a good half an hour on their website and it looks like agreat product and especially worthwhile for all you guys that rejet often. Dial-A-Jet

 

Interesting.

Got a couple of questions though.

1. It seems that you would have to jet your carb on the lean side, so that you could take advantage of the Dial a jet. what I mean is this product can only go as lean as your carb is jetted right now.right??


2. if #1 is right, can this be used for us Alky guys as well?

You need to drop the jet 2 sizes.

 

ahh ha! so i was right! cool.


So, does this [img]i/expressions/face-icon-small-happy.gif[/img]ial a jet affect the Pilot jet AND the main jet, OR does it just affect the Main Jet??
