Hi Phil,
Thank you for the information. I'm going to send the engine in and have a new case installed and purchase the needle valve assembly and get some head gaskets. Its a pretty looking motor and I'm glad to hear it will work out for stunt. I'll talk with Sharon to be sure we're on the same page. I was messing around the other day and weighted one of my merco 49 engine and with the tongue muffler the merco weighed the same as my OS 46. Yes, my merco 49 does make more power than my OS, could be just mine. I removed the OS and installed the merco, now I have a old sounding type motor and man what a ride. The merco 49 is like a kitten, she just purrs and this merco costed me $13.00?? Most look at the merco 49 and say why use it, the merco 49 is in the same case as the merco 61?? I use them, because they have a nice sound, start easy, don't use much fuel and they're a pretty motor, to me. I use only the lite case merco, the square bottom merco doesn't seem to run as well as the lite case. I really like the looks of the fox eagle, I hope she will run as well as she looks. I appreciate your help, thank you Gary
