Hello everyone,
I am waiting in mail my new Tower Hobbies .46 engine.
Is there anything specific I should know about this engine and how do I break it in right?
Thank you guys,
Valdis

To break in any ABC engine you wish to get it up to operating temperature but running it at a setting that is neither too cold or too hot. Differences in opinion exist whether your runs should be short,2 minutes runs with cooldown or a fuel tank at a time. I'll let you decide for yourself how you wish to do this. Whatever you decide for timewise, make sure that the engine is running past the 4 stroke break in a strong but slightly rich 2 stroke setting checking to ensure that the engine needle setting is neither too lean or too rich (pinch test while running verifies this). I would highly recommend a blended fuel containing both castor and synthetic fuel of at least 19-20% total oil content by volume.

Also, don't be worried if the engine won't quit by you close the carb barrel, this is a common occurance.
