I recently bought a spare p/s set for my NS12S3A1. The "book" calls for an 08604, BUT the spare sent to me was an 08606. I emailed Novarossi (still no response after a week), and talked to Trinity tech guys. Trinity says they have no listing for the 08606 and have no idea what it fits. Their book also says 08604 is the correct part #, but their site says the 08604 is for the RS series engines. Trinity says they THINK the difference between the 08604 & 08606 is one of them is AAC, the other ABC, but not positive.

The place I bought the p/s set from tells me the 08606 is what their "book" calls for as the correct set for the NS12S3.

Does anyone know which one is correct??? I thought the NS12S3 was an ABC engine and the NSR12 was the AAC ???
