Frequently Answers and Questions

What is the purpose of 'running-in' an Irvine engine?
Running-in is crucial to allow the close tolerance components in your Irvine engine to mate together under controlled and sympathetic conditions. This ensures sufficient lubrication and cooling without excessive load.
What type of fuel should I use for my Irvine engine?
The recommended fuel for running-in is 75% methanol and 25% castor oil. For sport flying, you can use 80% methanol, 20% castor oil, or 75% methanol, 20% castor oil, and 5% nitromethane. For contest flying, use a blend of 65% methanol, 20% castor oil, and 15% nitromethane.
How do I clean my Irvine engine after use?
After each operating session, re-fit the carburettor bung to prevent dust from entering the engine. Run the engine dry of fuel by squeezing the fuel line while it's running and emptying the tank. Keep the engine clean and free from dirt and dust, using methanol or a similar cleaner. Lubricate the engine with a light machine oil such as 3 in 1 or WD 40.
