This kit has all the parts necessary for complete installation.

Please note: All products listed in our OPLP cannot be returned for any reason. Please review pictures carefully. All product is new and/or “refreshed” but none of it has ever been used or put in service before. The revolutionary design of our newly patented Motor Snorkel (05/2013) has rendered these products obsolete. The MotorSnorkel eliminates cutting the frame, adding stud extenders to the carburetor, cutting and extending the crankcase line, etc. Because of these reasons most customers no longer want this type of propane and natural gas conversion kit, system or component so we are liquidating thousands of parts that were in our order pipeline prior to 05/2013.

Please look at the picture carefully. This Kit IS ALL NEW PRODUCT. This kit has all the parts necessary for complete installation. It is being sold “as is” to liquidate older stock. You will get what you see. 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 12 and 13 horsepower).

The center to center is apx. 2-1/8″ and the studs are offset at the 10 o’clock and 4 o’clock positions.

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.

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 and warranty are not available and will not be offered over the phone. However, our websites at MotorSnorkel and USCARB included FAQ’s and a very extensive technical forum that should be able to answer about any question.

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

Other than 48 States shipping buyer will pay the actual current cost.
