| | will it burn... I can remember putting kerosene in my dad's two stroke lawn mower back when I was a kid the FIRST time. So I'm pretty sure these engines won't run on kerosene but how about ethanol or french fry oil.
Just kidding about the french fries. Anything other than gasoline that will burn in the Chi Nee Caddy

| | Re: will it burn... There really isn't anything fundamentally different in the combustion cycle of these 2 cycle engines that will allow them to burn biofuels any differently than your average car engine. We could probably go down a bit in octane, or burn up to a ~20%/~80% alcohol/gas (various alcohols), you could add some toluene or xylene, a tiny amount of acetone - BUT BE WARNED I HAVE NO IDEA HOW THE ELASTOMERICS (HOSES, O-RINGS, GASKETS, ETC) WILL HOLD UP. |

| | Re: will it burn... Hi, you guys are gonna fool around and burn these things up? The critical thing here is good quality 2-stroke type oil in the mix to lube the ball bearings, and the bronze bushings.
These engines do not last all that long anyways, and to add alcohol (which burns hot and dry) is to send your little engine to Judge Roy Bean (the hanging Judge).
Mix well, ride easy, and save up for better engines as they develop would be my advise.

| | Re: will it burn... Go ahead and tip the Nitro jug I love the smell of burning Nitro and the noise!  
You can use methanol alcohol but it will need a major rejetting and special oil for the mix(castor oil or syn.) and they ain't cheap and your mileage will go down the toilet an alcohol is very rough on the aluminum parts the stuff likes munch on the aliminum and rough on seals. 
Cooking oil? Kerosine? all cost more per gallon than gas at least where I live but if you've gotta try it. I'd like to hear the results I could be wrong and it wouldn't be the first time.

| | Re: will it burn... We are speaking fairly hypothetically. Indeed it goes without saying....run a high lubricity pre-mix when messing around....at your own risk of course. When I used to run toluene or xylene/alcohol mix in my turbo car even then I would add some 2-stroke oil in my 4-stroke car! Simply as a UCL. Worked great.
If down the road I put any forbidden substance in my premix, it probably will be toluene or xylene as a octane booster. Just for fun. |

| | Re: will it burn... I've read a little bit on these engines and even looked into importing and selling them. I read somewhere on these engines that in China they didn't use a specific 2-stroke oil but an off the shelf auto oil for the premix and I've used 30wt auto oil in 2-strokes when I was a kid never heard of a 2-stroke oil then but I'm sure there was.
I know farmers used to run kerosene in their gas tractors as my dads international tractor Manuel had a section on how to start it on gas then once warmed up switching over to kerosene but his tractor wasn't set up to do that.
Last time I priced kerosene around $4.00 something per gallon in Nov.2007 I went to the airport and got jet fuel instead $20.00 for 6 gallons better price. I use the stuff in a portable heater in the garage. I'm lucky in that our airport is more laid back and everyone knows each other the way airports used to be before 911.
You might have something on the used french fry oil. a guy named Jimmy Glenn wrote a book on building alcohol burning Briggs for kart racing and he tried peanut oil as a lube and worked with good results but the price is as bad a the racing oil we used at around $15.00 a gallon so you might really have a good idea but if you burn up the engine that will ruin your day.
the wally world oil is cheap and works good for me but if a guy doesn't experiment no one will ever know you have to willing to suffer the out come.

| | Re: will it burn... Hi Norman, these engines have been Illegal to Import since Dec. 31 2005. 99 percent of what is being sold is SMUGGLED. Some time, maybe soon, the EPA will clamp down on all this Illegal activity.
I have NOT imported since the ban, Mine are legal, and I know of about 50 more.
I refused to be a criminal just to sell on ebay.
