Its funny you say that William, my OS 32SX's were bought as a pair, broken in as a pair and used on a twin where they ran identical. They ran great and always did everything together like idle, transition same top end and they both spit the nickle out within three tanks of each other in exactly the same spot just above the exhaust port. Now, to be fair, the 46FX's that had new ABN liners put in them (two of the three, the third 46FX was converted to the ringed version at my request), ran fine, but by the time I waited almost 8 months to get them back (HS did not have any parts because lots of FX liners were spitting the nickle), I lost all interest in keeping them long enough to do it again and were promptly sold.

....If they would only make an engine of the caliber of the Hanno's or the FSR's again.
