The generator is a 5500 watter with a 10 HP Briggs
The kit came from www.propane-generators.com
You have an engine they have a kit to fit it : )
Its a duel fuel adaptor and I can run gasoline or propane.
the adaptor fits between the carb and the air filter

Here is the adaptor showing the blocking valve
Thats sets the max gas flow to the engine.


The demand regulator that came with the kit is good for engines up to 60 HP It uses engine vacuum to regulate gas flow
This why the blocking valve is needed for smaller engines.

Here is the vacuum hose at the bottom of the carb below the throttle linkages going to the demand regulator.
All I had to do was drill the spacer block and install the hose fitting every thing else just bolts on.
If this carb had a idle mixture screw all I would have had to do
was take it out an screw in the hose fitting.
It is just that easy and it starts and run just like it did on
gasoline.
I like the idea of easy cold weather starting and a cleaner running engine
And propane will not go stale like gasoline when stored.
I am thinking of converting my snow blower next
