Roofer,
And if the manual
does not illustrate the best technique and is so generically written that it
does not bother even to distinguish between ringed and ABC/ABN engines (that obviously need different break-in techniques)??
Oh, you're saying; "Follow it anyway - it is enough that the engine will survive until the end of the warranty period...".
This engine should survive 400 running hours!... The warranty, on average, will expire after about 40 total hours... Are you sure you are getting what you paid for?
The 'F' in that clause you stated, is probably there, to show what religiously following that manual may lead you to do to the engine...
The [link=http://www.osengines.com/faq/product-faq.html#q2]OS Q&A[/link] specifically contradicts what the break-in instructions in the manual say, in regards to ABN engines.
