FWIW: My LMH 110 wouldn't run worth a flip with no CASTOR OIL. You didn't mention what brand of fuel you're using, but if it's pure synthetic, you'll never get the engine to run properly. I used Cool Power Pro Pattern 20/20 in mine with 4oz of Klotz Castor Oil per 16oz (I had a separate bottle that I kept and mixed it in).

Also, it has to be RICH. Mine was slobbering rich with raw fuel dripping from the exhaust as it flew. If I leaned it out any more, it would die. Power was good and it never quit on me as long as I kept it rich.
