I dont think the broken lug was from a crash. I think it was from being disassembled for some time sitting in my buddy's garage in a box with a bunch of other r/c stuff... T
I would put it on a stand and see how it runs. Sometimes, these engines are pretty tough.
I have it on the stand right now, I just couldn't get it to run for crap last time. I think 1/2 the problem lies in the needles - The carb was assembled when I got it, the rest of the engine was apart. The needles were in the wrong spots to begin with, so when I took it apart and put it back together, I put it together the same way it came apart. I switched the needles and I want to check the sleeve to make sure its in the right direction. (there is no locating pin on this sleeve) and try to run it again.. maybe tomorrow.
I am gonna stop and see if the LHS has any FAI fuel left and see what it costs for a gallon.
I broke the K&B in on 5% nitro fuel - about 1qt and then tried 10% nitro. It seemed peppier with the 10% in it, I grabbed the 15% because they say they will handle up to 15% and I figured the fox would run okay on it too. I have castor oil I can add to it. If I add 3oz of oil to a quart of the byrons fuel, I figure I would end up with a final mix of 13.7% nitro (all numbers by volume) 25% oil (47% of that is castor and 53% being synthetic) I know thats pretty oily, but it would get me by with what I have. Fuel is pretty expensive and I think my wife is about to pull the plug for awhile.. (lol)
I'll test run it and if I get it to run decent, I'll make a short vid and post it in the Fox forum and see if I got it right or not.. I'm still pretty new to airplane engines.. Some of these old ones run forever but can get finicky at times I've noticed.
Thanks for all of your help.. if anyone else has anything they'd like to add, feel free..
