SKU: K9151 Category:


Tri-Fuel that use an adapter installed between the carburetor and the air cleaner and do not require drilling the carburetor.
Includes a regulator with a push pin primer (purge pin) for purging and priming as a standard feature. 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 engines that are considered attended and used completely, exclusively, outdoors.

This Kit IS ALL NEW PRODUCT. It is being sold “as is” to liquidate older stock. This kit has all the parts necessary for complete installation. We do not allow exchanges of the adapter in this kit to fit other engines like we sell on our Motor Snorkel or USCARB generator conversion kit websites. IF YOU ARE UNSURE, IT MAY BE BEST TO PURCHASE A GENERATOR SPECIFIC KIT FROM USCARB. We have a 20 year record of outstanding customer service, but this kit is PRICED SO LOW because you will NOT receive service, help or warranty which are always included in our regular priced kits.

This Tri-fuel conversion kit will take your gas powered Honda generator to the next level. The kit is designed to work with the Honda GX series and Chonda Clone carburetors (mostly single cylinder 8-10hp).

The included instructions and supplies will allow you to modify your current ENGINE or GENERATOR to use propane, natural gas or gasoline. Given the tendency of gasoline to go bad or gum up the generator, having this option gives you great versatility. First, it can be used on the Honda engine it was designed for and on natural gas and propane. Of course, the gasoline option still is functional, however some carburetors will have a gasoline bowl vent that will be covered by the adapter which will not allow the engine to run properly on gasoline without first removing the adapter. (This is just another reason why the Motor Snorkel system is superior since it never has to be removed.)

We do not recommend or condone any alterations or misuse of our systems due ot safety issues. However, many people have used this adapter experimenting with different fuels like hydrogen, methane and biogas. (View USCarburetion Videos on YouTube) The engine regulator in the kit can handle from 4” to 14” water column inlet pressure.

This Kit is selling for almost half price, therefore tech assistance is available but will not be offered OVER THE PHONE. However, our websites at www.MotorSnorkel.com and www.USCARB.com included FAQ’s and a very extensive technical forum that should be able to answer about any question, if you still need help then you may contact us at the websites mentioned above and chat with one of our qualified customer service representatives or you may leave us a message.

Please follow the detailed instructions included with the conversion kit so this should not be an issue.
