I have a 20 year old fs120,new in box. I plan to put it in my ryan.
The o rings on the push rod tubes have become brittle an need to be replaced. Are they the same size as the newer surpass model? Or is a o ring kit available?

Thanks, wingsnh

The o-rings used for your older O.S. Max FS-120 pushrod tubes would be the same ones used in current engines.

These parts can be ordered through any hobby retailer who sells O.S. Max engines and accessories.
