High Quality Economy Kits

Tri-Fuel

and

Dedicated

PLEASE NOTE: D kits are Tri-fuel and do not require drilling.  The gasoline carburetor is not effected.  Again, no drilling of the gasoline carburetor is required for C and D kits.  Only the A and B Kits require drilling.

Economy Kits use exactly the same engine components as our Premium Kits.  You can dedicate the carburetor using the A and B kits or still use gasoline with our Type C and D Tri-fuel kits.  The cost savings on the kits is mainly due to the less expensive engine regulator that is used in these kits which can be produced at a much lower cost.  We are pleased to pass the savings on to you.

How can I order a kit?

The newly designed economy kits still provide full power and performance.  We simply named these "Economy" kits because they do not sell for as much as the premium kits and are as much as 1/2 the price of our Premium Kits.  Due to the misunderstanding about the term "economy", we are changing the name to "standard" very shortly.  The price difference is not because they are cheaply made.  Actually the kits include a quality regulator that most other companies are selling at a premium price. These kits are excellent to use on generators that have a governor controlled throttle and yes, the throttle speed control switch will still function the same as it does on gasoline.

The most common question we are asked is, "What is the difference between the Economy Kits and the Premium Kits?" 

The Premium Kits utilize a heavy duty industrial type engine regulator with an internal idle circuit (this idle circuit which has an adjustable idle fuel screw is needed mostly for engines that have true throttle control like a pedal operated throttle or a lawn mower) and an additional vacuum safety shut-off device built right inside. Vacuum from the engine opens this lock-off to start the fuel to run and stop the fuel when the engine stops. 

The Economy Kits come with a "zero governor" that acts as its own shut-off device.  Think of the engine regulator as a glass of milk and the rubber hose from the regulator as a drinking straw.  If you put a straw into a glass of milk, no milk will come out of the straw until you draw the milk up the straw.  That is how the zero governor functions.  When the engine is running and as air is passing through the carburetor or adapter, the fuel is drawn out of the regulator through the rubber hose.  When the engine stops the gas stops.  But as you will read below, the National Code states that this is acceptable for engines used out of doors and 12hp or less that do not have a distributor cap (which is basically all small engines).  Over 12hp you have to use an additional lock-off device no matter what.  If you have electric start on your engine you could add our RSK-LP to the economy kits and then they would be acceptable up to 23hp.  But for all engines all of our premium kits have the additional vacuum lock-off as a standard feature.

As you can see the economy kits do not need additional vacuum lines and fittings so they are  simpler to install than the premium kits.  The same carburetor and adapter components are used in both the premium and economy kits.  The only difference is just the engine regulator that changes and the associated parts.

A & B Kits     C & D Kits

Click on the left picture to see what the average A & B kit includes and click on the right picture to see what the average C & D kits have.

A & B kits are dedicated low pressure propane and natural gas and require drilling the carburetor.  The C & D kits are Tri-Fuel and use an adapter installed between the carburetor and the air cleaner and do not require drilling the carburetor.  Other differences in the kits are that the C & D kits include a regulator with a push pin primer (purge pin) for purging and priming but the A & B kits do not.  You can request one for the A&B kits for $15 extra. Just click on the ADD PRIMER link below.  No mounting bracket is needed for the regulator.  It has two mounting lugs and will allow it to fit on just about any generator by drilling two 1/4" holes in the frame (as shown in the picture on the right).  There are also two threaded holes underneath for bottom mounting (shown below on the left and center pictures).  The engine regulator has a 3/4" FNPT, female fuel pipe inlet, mounting lugs and mounting hardware, fuel delivery parts for use at the carburetor, hose, clamps, and other fittings for compete operation (less hook-up hoses of course).  Again, these kits are for up to 12hp engines that are considered attended and used completely, exclusively, outdoors.

To order these kits, your application must meet the following national criteria:

NFPA 58 (1995 edition):  [The regulator used in these kits can be] used for portable engines of 12 horsepower of less with magneto ignition and used exclusively outdoors shall be considered in compliance . . .[the regulator used in these kits] shall be considered as automatic shutoff valves only in the case of completely outdoor operations, such as farm tractors, construction equipment, or similar outdoor engine applications.

The kits are engine complete and do not have hookup hoses or connection lines  For hook-up to portable cylinders, the use of an NPSK accessory is necessary.  If connecting directly to a natural gas or low pressure propane line then a hook-up hose is necessary.  Follow the links for prices and descriptions.  These kits are not recommended for engines that have throttle control like on a lawnmower because they will work but may not keep running when the throttle is lowered to less than 900 rpm.

If there is a  Yes link in the column a kit is available for your engine or generator and clicking on the link will automatically add that kit to your shopping cart.  To add an NPSK accessory or hook-up hose choose "Continue Shopping" after the kit is added or use the links above.

Shipping charges for all economy kits and accessories anywhere in the continental USA is $8.50.

Since these kits are newly introduced, we are in the process of adding engine model numbers and generator brands and model numbers as we have time.  If you do not see your 12hp or smaller engine on the list, please email us and we will promptly let you know if yours is available in the economy style.  Please specify if your interested in either dedicated or Tri-Fuel.  There is a kit available for your unit if your engine or generator is listed in our premium kit list and has a YES link in the Type 3 or Type 4 column.  Simply order a Type B kit to substitute for a Type 3 kit or order a Type D kit to replace a Type 4 kit.  When checking out our shopping cart will ask for your generator and/or engine model and you can type it in there
