RE: YS 61 LS
Well looks like this thread may be for not. I ordered a few parts from SG engines yesterday morning, a thrust washer for my Rossi 61 3+2 and an exhaust adapter for this YS. Sahak at SG called me within 2 hours to verify the order because he realized that no Rossi engine was going to accept both the parts I had ordered. Once I clarified that they were for two seperate engines we got to talking. I told him I had been running Rossi's in my race planes but needed a little more out of the 61 and was looking into the YS. He offered his assitance to the point of consulting with the techs at the Rossi factory. Looks like I will be rebuilding the YS stock and then installing it into my Classic pattern Dalotel. Thanks to the guys who offered suggestions. Looks like I will be sticking with Rossi in the race planes.
