yes I converted my generator, actually two of them,
I used the TRI fuel kit, as I wanted to keep the gasoline option, (problem is the change with the LP unit added change the unit such it is nearly impossible to get it started on gas, it will run on gas once started, the other generator, I used a fork lift LP conversion kit I got off of Ebay on it, it is a larger multi cylinder engine,
I ordered the additional Safety Shut Off, as I have a generator shed, I do not remember which company I ordered from,
Generator Conversion Kits to Propane and Natural Gas.
Generator Propane Conversion Kits & Natural Gas Conversions
an electric start would make starting easier, as they work on vacuum and you have to push a pin to let propane flow for a given set of seconds, (like priming it) and pull the rope. Safety shut off your pushing two pins, with electric start, it just makes it easer as you crank it and push the pin, and she runs, ,
usually with two quick pulls, once one gets it figured out it starts reasonable easily.
and on the larger generator, it starts very easy with the electric start,
(In theory to properly set the carburetors, one need a meter that reads the CO. of the exhaust, on the larger engine I know I did, do not remember on the small 8 HP motor.
follow the info from the manufacture and you will most likely have a good conversion,
I think if I was doing it again on my small generator I would get the propane carburetor that replaces the gas carburetor and set the gas unit aside for use if ever needed, and not go with the dual or TRI fuel set up,
