A little scary without a gas regulator...:hide: ....But Uncle Rube would be proud !
----------------------------------------------------------------------I went out to split some wood last weekend with the log splitter. As I was filling the gas tank I heard an unusual sound. I looked down and there was gas pouring on my feet. While I have been waiting for a new gas tank I bought on Ebay, I decided to play with some propane. Engine is an 8 hp Briggs. Pictures below.
While this looks a little hokie, it worked perfectly. Takes a little extra effort to balance the engine throttle and the gas valve. It has run for at least an hour and I did not run out of gas in the little tank. In the near future I am going to make something more sturdy out of copper or brass.
Are you using the orifice from the propane torch too,or just a hose slipped over the tube that holds it with it removed?..neat setup,a home brew vaporizer!..I've read how to use propane on Walbro carbs easily on the www.theepicenter.com site before..seems to me I remember Briggs having some LP gas engines factory that used a Flo-Jet carb,modified with a regulator..
Wonder how long it would run on a 20 lb gas grill LP tank and the regulator from one?..
My last eperiment with propane was scary--tried using a propane torch (un-lit!) to help get my old continental 4 banger fired up after sitting too long unused,by putting it in the carb throat ,kinda like starting fluid..it just spun over for a long time,then suddenly a huge WHOOF and BIG flame came out of the exhaust manifold,and my eyebrows were almost history!..decided to call it a day,and try another method to get it to start some other day!..
