The Flo-Commander ties/blends each of the carburetor's fuel to air mixtures to one, Thus eliminating the results of uneven air pressures around the carb air jets causing the multiple fuel/air mixtures of the diff. carbs to thus be much better synchronized through-out the entire RPM range (approx. 3000 to red-line or 1/16 - 1/8 throttle position to W.O.T.) instead of just at idle. You adjust the fuel/air mixture of all the carbs at once by adjusting the thumbscrew to add or limit the air going into the main circuit. The carbs in which we remove the main air-jet to install the tubing adapter have a carefully sized and shaped restriction inside the tubing adapter. We use this, and use the same restrictions already in place (on the carbs we just press the adapter down over the air-jet), to ensure that even if the flo-com. adjustment is opened way up it won't be dangerously lean. When opening it all the way, it does allow a certain amount more air through (to go slightly leaner in the mixture) because even though the restriction is the same size, the other effects such as air velocity & flow, in the tubing, allow / enable it. You then have a more broad range of adjustment.

The first sought after, and now acquired goal, is smoother circuit-to-circuit transition areas, as well as much better synchronization. The next sought after and acquired goal is being able to adjust (to a certain degree) multiple carburetors from one point.

End result; more TQ & HP, a more smooth and predictable power curve, convenience of tuning, the flo-c. will aid in determining where your jet size should be, if you make radical engine mods, while allowing the finer adjusting to be done with the unit itself. How much power you gain will vary , but, we have seen averages of 2 or 3 in a few areas, up to 10 or 12 and higher in others. An over all average gain in a particular situation, as long as the installer of the Flo-Commander at least average skills as far as a conscientious mechanic, and (DEPENDING ON WHAT WORK HAS ALREADY BEEN DONE & HOW CORRECTLY IT WAS DONE) has been somewhere between 4 & 6 hp , and so importantly a MUCH SMOOTHER application of that power.

Tubing Adapters This is the specially designed fitting (per application), that allows the tubing to be easily attached to the proper location on the carbs fuel/air circuit. This shows the "Tube Type" OEM Air Jets or Restrictors. They are not removed, as our tubing is designed to simply be pressed down over it as shown.
The OEM type restriction seen below is removed & replaced by our adapter.
"Jet Kit" Plugs & Restrictors. The plugs or restrictors can have a counter-bore in the top, so you need to look down inside of it to tell which it is, but it's no problem whichever it is! It's all covered in the clearly illustrated instructions.

If have installed a ?Dyno-Jet? Jet Kit, you may have a plug or restrictor in the main air passage. This is a list we have compiled so you will have an idea if you will need to remove a plug or restrictor so the passage can be used to it?s original flow potential again. You will be able to set up the Flo-Commander w/no problem, no matter what jet kit brand or type you may have installed. The list here is handy, as it will tell you if you should purchase our handy super time saver Plug/Restrictor Removal system. You can remove them without the system, but the few bucks for the system is well worth it even if you only ever use it once. They are just a convenience we offer to you. If you have another brand/type Jet Kit, the passage is most likely not plugged or restricted. As a ?rule of thumb? if you are removing a restrictor, and the jetting was ?Right On?, you can go up just one size on the main jets, to bring the mixture back into a neutral position, and fine tune with the F.C. If you remove a plug, you can go up 1 or 2 sizes with the mains and fine tune with the F.C. These are basic settings/suggestions. You could make up the difference with just the F.C., but because you would be closing it substantially to get the mixture back rich enough, you wouldn?t be getting as much of a synchronization effect, as you would not be allowing the circuit to be utilized as much.

Many times though we have found that the Jet system installer, did not put the plugs or restrictors in anyway, in which case it?s an extra easy install.
