I am in need of a carburator cover, spark plug cover and the carburator knobs for a 1946 Wizard WD4 (or a 1946 Mercury KD4). If you have any of these or know where I can obtain them please let me know as I need them for my restoration. Thanks much....Keith Campbell PH. 810-329-4372 or email me at the above address.
Those are scarce parts indeed. If push comes to shove you can try my substitute knob idea employed on a WD3 motor here:
You could try looking for Mercury KD4 parts also here:
I don't know if you will need deep pockets or not.
Just a note:
both spark plug covers are not exactly the same.
Hello Bryan: Thank you for the follow information for my WD4 Wizard. Since these exterior parts can be added to the motor once found I will proceed with my restoration as is. Your input on the knobs is novel and kinda neat. The pictures you sent me of the spark plug cover was very helpful. A note to all...please contact me if you have the parts I requested. Kind Regards: Keith Campbell 810-329-437 email@example.com
Here's a link to what the cover over the Carburetor should look like from my WD4S motor I purchased from Ebay:
