Tbone,


You must first learn to operate your engine.
This is best done by mounting and running it on a test-stand (a makeshift test stand will do, just make sure it is sturdy enough to withstand the thrust and the vibrations).

You must learn to respect it; not to fear it.
It will not bite you unless you annoy it...[>:]


It is NOT ready to run, unless it was previously used by someone... And even then, it may not be ready yet.


Please state the make and the type of engine and we will give you good instructions, for doing the break-in properly, to achieve a long and reliable engine life and top performance.

Different engine types require totally different techniques for proper break-in and some engine manufacturers supply 'generic' instructions, that are not type dependent, which may only be good enough to get the engine through the warranty period...


In any case, as Jim (w8ye), a model engine would sustain no damage from being turned backward...
