RE: New Evolution 10cc gas engine
The black break-in goo is still there but at least now I have it diverted away from the fuselage while I'm breaking it in . As already stated it will be there for awhile and after I run a gallon of dino oil mix through I will switch over to Klotz oil and should have it in the air by then.
Before I test the 13X6 prop I'm going to take the muffler apart and see what I can do to seal-up all of the seams and bolt holes as it leaks worse than a glow muffler.
