Dial-a-jet

[snowdog]

If you are installing the dial-a-jet are you supposed to jet it with your mods first before you add the sysem and then step down two or three sizes when you add the system?

[blk02banshee]

YES. And for the dial-a-jet system to work the way it's supposed to, the brass tube needs to be perpendicular or perfectly 90 degrees to the bore of the carb. If it's even slightly angled to the front or back of the carb, it won't act right. And welcome to the HQ!

Now I was told that you need to step down two jet sizes after it was dialed in, and if you went three it would probably be fine and would probably make it run richer. Is that right? I thought if you were down two sizes and it was fine then if you went down one more size it would let a little less fuel into the mixture and run a little more lean not rich. Or do I have this backwards. Man-o-man jetting

you do have it backwards. if you have more oil than gas your rich.

less oil than gas=lean.

Maybe I am not understanding you right ish, but the less fuel you have, the leaner you are. The more oil you add to your mixture, the leaner you will be. Lean or rich isn't necessarily your gas to oil mix, it is your fuel to air ratio.

I guess I wasn't clear as to what I was saying, but yes I was talking about Fuel and Air mixture not oil to fuel. The oil and fuel mixture doesn't have much to do with jetting, unless you put so much oil in the premix that you are starving the engine of fuel, or too little which would cause no lubrication, but that is an entirely different problem.

 

But I thought that if you increased the main jet size you allowed more fuel to flow through the jet and the higher the needle was, that much more fuel would even run through making it even richer.
