Green Mods, Gas Mower to LP, H2? Hey All,

I have a pair of mowers with 6 HP Briggs %26amp; Stratton motors.

1 runs well, the other I%26#039;m trouble shooting.

I was working on the broken one today and just happened to spot the propane tank sitting in the corner of my garage.

What would it take to convert? Does anyone sell a kit? Whats the trick to doing this safely... Obviously if you just pump gas into it, good chance it will run if the flow is right, but say you start the gas and step away for a few minutes before starting the motor.... I would expect a fireball from the propane thats been blowing out the intake.

Other suggestions, fuels to play with?

My only concern is I don%26#039;t lose any HP, 6 HP is often barely enough for the thick spots if I haven%26#039;t mowed in 2 weeks.

Wouldn%26#039;t mind tuning it to get some more HP

I believe propane isn%26#039;t nearly as volitile than gasoline.

I%26#039;ve seen plenty of people just use a regulator and rubber hose to the carb to do this, but seems there would be a safer way.

Not really looking to save money, but LP is cheaper than Gasoline by far.

I think I spend all of about 10 dollars in gas for my mower a year, have a small lot and usually mow once a week in the spring.

I have a popane tank sitting in the garage that I%26#039;ve used to fry 4 turkeys in the last 2 years and its still got plenty of LP in it...

NO, NO, NO, NO, NO propane is NOT a good idea. With a serious conversion kit where fuel can be injected and regulated propane can be injected but not used as a stand alone fuel. Propane is highly volatile. A 2 cycle engine like this could not handle it. For more information check out some of the many sites for propane injection. Besides, propane consumption to gas consumption, where would you save money anyway? 100% 2 Votes

• With small engines conversion isn%26#039;t really practical. The best thing you can do is replace the engine with a 4-stroke, because 2-stroke engines send unburnt fuel out the exhaust pipe. 0% 0 Votes
