    OS70s throttle arm ring disconnect

    While flying yesterday I soon lost throttle control after T.O. so I had to run out the tank before landing. The engine inspection shows (1st Picture) the throttle arm ring had popped off. I don't see how this is attached to the carburetor assembly other than just a pressure/friction snap????? The second picture shows the arm snapped back on, but it is not really secure. The third picture is of the carb and arm assembly on my OS91 just for comparison.

    What are my options for a fix?

    The throttle arm was held to the assembly with crimping. Here's the stock number and retail for a new one:

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