Coleman 8HP B&S 4000-Watt generator Propane carburetor.

I recently have been tinkering with older small generators that I have, and I am a fan of converting them to propane. I came across a legitimate used propane fitted carburetor with the demand regulator that will fit this engine on eBay.

Has anyone ever run such a setup on one of these old 8HP generators? The engine is the horizontal crank flathead design with the large Flo-Jet carburetor

There was nothing that I could find when checking the internet for a similar setup.

I hope to have it setup to test run in the coming week or so.

Any info is welcome.

I know it will not be able to run on gasoline in the future once converted if I use this setup.

Hello folks

I had a medical setback, but I'm still looking for any information that may help when I get back into this project after I fully recover.

I'm sure there are some older small engine folks out there who have seen this 80's setup.

To me it is rather unique and I would like to get it going, but I already have other (newer) portable B&S storm responder generators that I have converted to run on both propane and gasoline.

This one might be used mainly for mobile repair jobs and stay on my service truck because all I ever need in those circumstances is 120V.
 
I am still healing but am now home searching around for possibly a different carburetor design that will fit if I use a heat shield to protect it from the adjacent muffler.

While I already have the converted propane carburetor, that is nice, but....

The appeal is also still being able to run on gasoline if needed in a pinch. I like the ability of dual fuel, especially in cold weather when propane can be moody and not expand enough to come out properly.

So far, an 8-10HP Tecumseh carburetor might work because the fuel inlet is opposite of the muffler. If that will work, then a motor snorkel kit can be adapted to run propane.

Being that a throttle control will not be needed except to hold a steady 3600-3700 RPM, that should not be too hard to accomplish.
