Default SIDEWINDER FUEL HELP

I have an associated gt2 with the stock .15. I have been running odonnel race fuel with great temps and power. I had to buy a gal of morgans sidewinder, (all the lhs had) and they swore it would run better than the odonnel. I cant get this crap to run at all. It only wants to run 300 degrees, if I richen it up it want rev at all. My question is, is it possible my engine just want run this? I switched back to donnel and back to awesome again.

Which blend are you running? The Worlds or the Pro blend? Are you sure your temp gun is accurate? If your engine has some wear it will more than likely not like the synthetic Worlds blend..

I run worlds blend in my .21 GRP's and I love it I have used approx 12 gal exclusively 7 on one engine last year and the other 5 this year on 2 new GRP's. It has been my experience that the opposite is true when I use Odonnell's my engine runs hotter. I dont know, but Sidewinder has been great to me and no after run oil at all.

I dont mean to really say the fuel is crap. There are thousands of guys running this and doing awesome. The no after run oil was one thing i thought would be great to. Im just more confused. Some guys at the local track said that this was a fuel more designed for larger engines and is a hotter running fuel. I also tried a couple of tanks of byrons gen2 with a lil adjusting it ran good to. I did have to run it a lil fatter than the odonnel.

I have been running the sidewinder for the last 8 mths with zero issues. best fuel I have ever used IMO....I used to run byrins original gen 1 with great results but hated the gen2 maybe a bad batch in the begining who knows? but I also run 1/8 buggy and truggy. altough I did run the 30% in my nitro boat and my sons 1/10 nitro truck...

I just switch from O'Donnell to Sidewinder World's 30% also, It was the best change I have ever made IMO. I had to make very few adjustments on top and bottom end. I run OS. Speed in my truggy and buggy, they both accepted the fuel change with great results. Both engines have 1.5 gallons each run through them. Did you change any other thing besides fuel(fuel line, fuel filter, air filter, glow plug, etc....)?

It is very common to put in a different fuel from another manufacturer and your motors tune is out of whack. The oil content could be different, castor oil vs synthetic, just to many variables. I have noticed that some times it takes a tank or two before the motor gets used to the new fuel but still some tuning will be required.

I've been using Sidewinder 20% Race Blend in my OS .12CV-R and my various .21-.28 mills with great success. Holds a tune well, temps are fine, and it keeps things well lubed/protected during extend down time (sometimes go a couple of months between races due to life gettin' in the way). Never gummed up or rusted the bearings since I switched to SW (and I've not felt the need for ARO).

Me and yeaklet 4 are having the same problem. I cant think of anything that i have changed other than the fuel. Another thing all you guys sound like your running big motors .21 .28. Is it possible that these motors can handle the fuel and my .15 cant. I looked at the jug i am running 20% pro blend.

My little OS Max .12 CV-R has ran on Sidewinder 20% Race Blend almost exclusively, and loves it. My TRX2.5R (which is a .15) ran fine on it as well. Strange that you're having this problem...

I havent tried it yet but i am thinking I need to lean out the low speed and richen up the highspeed. When it is on idle it is dumping a ton of fuel out.

I'm using 20% in my Novarossi .12 in a CRT .5 and it usually runs around 220 with great power.
