Jess,


Most people have very little patience. Sometimes I do too.

In trying to trust what the manufacturers say, there are pitfalls.

Try reading the OS manuals for the FX/AX engines and compare them to the OS Q&A and Bax's words in the support forum.

The manuals say to run the engine at a four-cycle and occasionally at a two-cycle, then back to four-cycle, while both other sources say to run it at a rich two-cycle only...
So which are you supposed to trust???

The Super Tiger manual specifically says (about ABC models), to run the engine just beyond (lean of) the point it breaks into a clean two-cycle, as does the manual for the K&B Screamin' .48 ABC.

All the documents mentioned are on-line and you can see them where they should be.

With most of what the manufacturers say (those who speak with a single voice...) and what has been published in model magazine in the last 15 years, or more, there is a general consensus about the right way to break-in a tapered-bore engine.

Those manufacturers that tell you to do otherwise, just want to sell you an expensive piston+sleeve set ASAP. Much earlier than you would need it, if you do it the right way, as posted by someone about car engines, earlier in this thread.


Why should I wait for Brian (downunder) to go through with getting the results?

The worst case is that he will get an engine that is not up to its intended performance, as posted by another member and at best, he will be getting similar performance to an engine broken-in correctly, after having wasted a lot more fuel and much more time.

I doubt that even he thinks he will get any tangible advantage from this endeavor.
