How to clean varnish off a glow engine?
I have been flying for approximently six years. I have several engines that are covered in varnish and their performance is suffering. I have just oppened an evo 1.00 and the piston was covered in brown and a little black, like tar inside.
The last three years I have been burning Wildcat 15%, that is 80% synthetic and 20%degummed racing castor.
I have had good luck with this fuel and would like to keep useing it.
Please help, I have heard that there are products that you can buy at wall-mart that will clean engines up.
Thanks for your help
