Pulling the head (jug) is beyond my ability. I would not know what to do with the jug after I had it in my hot little hands.

What I have done is taken Wayne's advice and filled the engine up with carb cleaner and turned it over until clear. I actually used some morot flush and ran 4 cans through the engine before it was clean. I then took Marvel M Oil and coated the inside of the engine and then turned it over and sat the engine out in the sun.

I put 8 flights on my plane today and it seems to run strong and rich. I will run a couple of gallons through it and see what happens next.

Wayne, also to answer your question about stabilizer, I was told that gas could go bad sitting around for a month. I was suppose to go out of town a couple of weeks ago and figured I would be safe that sorry. I have gone though 20 gallons in 6 weeks so I will agree, I don't need to add stabilizer to my fuel!
