Try running low nitro fuel. It will run just fine on 0% or 5%. Plus you'll get better fuel economy on cheaper fuel.

I usually take 15% for my combat planes and 0% for my Foxes. When I mix them up the .74 becomes very tempermental.


If you have the EZ, air bleed carb, look in this thread, post 545

THis carb modification worked for my 74. The EZ carb tends to lean out in the mid-range then overheat.

The was an informative site that has since gone down called flitelinesolutions.com. I copied some of it to my clubs webpage at [link=http://www.fayettevillercclub.com]www.fayettevillercclub.com[/link]
Navigate to the Fox Engines page and the fix is detailed there. Let us know if it works for you.
