Thank you very much for your current response to my query, and also for your efforts 4 years ago in writing that very elucidating thesis on ABN engine break-in. I will use the method described there-in. It appears that this case justifies an exception to my long-standing tradition of accepting the recommendations of a manufacturer over the advice of other specialists.

I think if you you go with Dars or OSs method you will probably end up with a nice running engine. If you look at the manual it says to run the engine with the throttle fully open for a minute rich and then alternate 4c and 2 c at 10 sec intervals. Now to my mind this doesnt mean run it so rich it doesnt even warm up but to my way of thinking its more a heat cycling method instead of running it 2c and then shutting it down to cool off. Now if the conrod was about to explode with this initial rich running why would all the 2 s engines I have say to slowly warm the engine up instead of immediately go to full throttle 2s running? Now I have my crash helmet on and am ready to be shot down. Cheers the pope
