Since our last contact, I have finished installing the conversion kit on my Coleman Powermate generator. I was a little worried about starting it for the first time. But...It was like you said "no problem". This thing runs like a fine Swiss watch. Idle is slow and power seems unchanged. It also smells "so sweet". I have digital pictures of the completed system if you are interested. Thanks.....

I recently installed a type 4 kit on my Yamaha 2800i and am very pleased with the result. I am not very knowledgeable regarding generators, and US Carburetion staff were most helpful in answering my questions and helping me select accessories. It is a pleasure doing business with such a professional outfit. Prices were also much better than other dealers for comparable products.

I put your kit on a Generac 4000xl four years ago (1999).  Still works great with one to two pulls.  Now need the upgrade and want the electric start for remote starting.

Just a note to tell you how well things worked out.
The engine runs better on Propane than it ever did
on Gasoline. I am surprised at how responsive it is
to abrupt changes in load on the generator.

I think this would be a neat picture for your Web site,
it illustrates the connections very well, and is
different from the high speed one lungers most people
are using.




The tech service department is exceptionally responsive and tolerant of novices like me who are installing these devices for the first time.  The kits are very easy to install, but if there is a problem these guys are back to you in almost real time to keep the installation moving along.  They were even able to determine that my local gas company hookup was causing a problem with my generator accelerating through e-mail.  The bottom line is great product, great service, a really reasonable price and nice people to deal with.
