This generator conversion kit is actually more of an adapter than conversion. This kit will adapt your generator to use both High Pressure Propane and standard Gasoline. people often ask about power loss with the adapter style kits. We have never had a complaint about power loss with any of our kits.
After the installation, the engine should be tested right away on gasoline. If a reduction in performance is noticed on gasoline you may choose to remove the adapter when using gasoline. This usually takes only a few minutes though it is often not necessary.
