RE: Trashed my new motor after break in!!
the thing with most novarossi engines is they come from the factory with a rich LSN and a high iddle setting wich can give you the impression that you're LSN is set properly because it isn't cutting out and the HSN is extremely rich, but this isn't the case people tend to over compensate for the rich lsn by leanning out the Hsn and unless you do really long straight line runs you will not notice that the hsn is way too lean.
My trick is to set the iddle as low as possible before tunning the hsn that way, you're sure that you're lsn is set properly.
sorry bout the engine, it still seems odd that it would break after such a short period...
Contact Novarossi and tell them you followed the manuals break in procedure they may try to skip out on you if you admit that you used the heat cycling method.
