RE: Engine cleaner
Go to your local automotive shop: Discount Auto, Autozone, Pep Boys, or even K-Mart or Wal-Mart, and buy Marvel Mystery Oil (Red bottle). Take the motor apart and oil it with this. Then after that run a few drops of it in the tank of gas for the first run. This will add more oil content to the nitro to help the motor recover from the long sit of no oil.
