Josh, I hope you will see this but here is my question with your method.

I tried it step by step but that engine died in the middle of a race--a broken piston. Luckily it was a handout motor ($50 for race entry includes a motor). It wasn't the best motor out there so the failure could've been due to material or worksmanship.

But looking back, I see a problem. You stated that once the engine is up to temperature, we should richen the top needle until the engine flames out. Well I had to open it so much before it flamed out that the engine cooled down and was only running at about 100F. That couldn't have been good?

Also, as mentioned in other posts before, wouldn't full throttle for 5 tanks especially when the engine is tight and temperature is lower be bad for the con rod? I mean yes replacing it is always a good idea but having to replace a $20-$30 con rod right after breaking in seems a bit excessive doesn't it?

I hope you and everyone don't take this the wrong way. I am just curious. Please let me know if I am not following your method correctly.

And if you actually saw the post, good luck with the Reedy and I can't wait to see that new Kyosho car!
