Wild running wd

[handcrank]

My wd starts right up and runs full throttle. Throttle lever has no effect. Linkage all seems to be intact. Any help appreciated. Thanks.

If you have not done any work to the carb or carb linkage, I'd say your governor weights have exploded. DO NOT start the engine again until you inspect them.

This is all new to me. How do I go about
checking this out, step by step. Thanks

You should probably get a service manual......if the governor weights have "exploded" you're probably going to need it.

If you remove the plate on the front of the timing case cover, you will be able to look directly at the weights.
The plate is held on with only 4 bolts and is simple to remove.
Maybe.......maybe......you'll be very lucky and the governor is OK.
