Thanks for advice guys! I had not realized how much engines have evolved over the past 20 to 25 years. The LA 46 will be sent back to Tower for a refund. I am not impressed with the construction of that motor, and I am a bit surprised O.S. put their name on it... I will put the old Fox 35 on my FS, and live with it's vibration and poor performance for a while. I now have a Thunder Tiger 36 Pro which shares the same mounting dims as the Fox, so if I ever decide to go fast with the FS, the TT 36 is a drop in.
