Briggs 18hp opposed twin

These tractors were built about 30 years ago. The engine is probably a 422437-1266-01 or similar type.

This has a simple link (pn 690554) located between the governor lever and the 3 screw carburetor throttle shaft. If the carburetor has been changed to a 4 screw, the link is 693543.

The control bracket (691366) is no longer available from the distributor, but may be available from old stock dealers and the auction site.
