What type of fuel are you guys using on a Hanson 26 modified motor?
Gas or Camp fuel. My buddy is installing this engine in his predator and was told only to run it on gas.
Anyone doing diffrent?

Thank you all

I am running Camp fuel, on my Hanson 26 modified, because it does not smell and it runs great!

Gas for me

Because the smell isn't an issue and gas is easier to get and 1/2 the cost.

I have been around 2 stoke engines (moto-cross) for 20 years. We have always ran premium gas with Yamalube "R" oil mixed at exactly 40: 1. Thats 1- 16 ounce bottle to 5 gallons. I still race motorcycles and have a modified 250cc 2 stroke. The last 5 years we started running 110 octane racing fuel straight (w/oil) with no problems. Whether running straight gas or racing fuel the most important thing to watch is NOT running to lean, we were always taught the best way to do this is to watch the color of the plug. It should be somewhat light brown or tan color, not white. I have always ran the 110 octane in my predator gasser and have had no problems. Also another combination is half premium gas and half 110 octane. I know some guys will think this is a little odd. But a 2 stroke is a 2 stroke is a 2 stroke and we have NEVER burned one up in all these years because of to high octane. Hope this helps
O yea, one other thing the smell is awesome !! Its like a totally
different smell, kinda like smelling roses, Ok maybe not that good.

This is NOT! I say is NOT! the best way to read if your motor is too lean or too rich, most people 99% have been taught wrong it is just OK! the best way is to look at the color, of the top of the piston that is 100% sure, I have been involved in high performance 2 stoke motorcycles for over 35 years and believe that is the best way, all the top factory mancancs do it that way, all the dyno ruus I did using High octane fuel on low compression motor we have loss! HP and it is a waste of money.

I would agree for the most part on what you guys said. A couple things though, mcfast your saying take the head off to check for
running to lean? I could see that as being a more "exact" way. When we start to rejet a bike for instance, its much easier to take the plug out and check instead of the head to get a general idea. The plug is at the top of the head so it should give some direction as to which way to go with jetting. I guess when one gets the plug
"close" then he could take head off to fine tune. I get your point but taking a head off every time would be time consuming especially on a heli.
About the fuel octane, I forgot to mention I have milled heads on the 250cc bike and the Hanson 26 modified, thus bringing the compresion up a tad. Of course most guys dont have milled heads
but I have heard that mixing high octane with regular gas, 50/50 works great on stock engines as well as modified.

T.Fiddler your saying that even a mixture that is 50/50, (high and reg. octane) in a stock engine is not as good as running a low octane? I am not a dyno guy so I would be interested to know what you have found in those 15 years (toot toot) Also is there a formula that has for so much compression you would use so much octane?? I know what i have used in the past and works but would like some input. It looks like a mixture of half and half would be better than reg. 87 octane in even stock heli engines ? Any input would be greatly appreciated !!
Dont get me wrong guys, I am definately NOT a know-it-all and Im
ALWAYS open to comments and suggestions. I do know what has worked and not worked in the past for me, the hard way sometimes, and am always open to learning more. That is one reason why im on RR, to learn more and share any ideas or experiences that ive had. One thing I know for sure,
I love flying 2 stroke helis !!

For sure if we were trying to get 100% out of are motors this would be the best way to do it "jetting and octane adjusting" but for just flying around and having fun, we just have to be close on jetting and all most any octane will work, just keep it simple and cheap and what works for you, that is all you need to have fun.

You should never run 100LL in a 2 stroke, 2 stroke hate lead it fowl up the spark plugs, 10 years working on Rotax airplane/ UL engine, even took my corse at Rotax in Austrie.
