I have just become the proud new owner of a 1946 wd4. Everything is in excellent working order. It took a little bit of cleaning on my part, but the motor cranks just fine and runs well. I was rebuilding my carb and i broke my needle valve into two pieces. It split in one of the grooves for the keepers that keep the float in position. Does anyone know where i can get a new needle valve? Will i have to get one machined? Would i have a shot at buying the used part, and if so, where should i look?
I don't think you'll be able to get a new valve...you'll have to track down a used. The WD4 is based on the Mercury KD-4, and I would recommend posting a wanted ad on the AOMCI webvertise page. You can also try Doug Penn (Douglas.Penn@gmail.com), who sells used parts for vintage outboards (google him for his website). He's a great guy and has good prices.
My brother has a very limited supply of NOS needle valves for the early "K" model Mercury Outboard engines. I called him earlier and he sent me pictures which are posted below. He quoted me a price of $15.00 including S&H. If your interested, please e-mail me at firstname.lastname@example.org
Here are the pictures.
Sorry Jason, not the right part.
I did get in touch with Doug Penn. He described the part that i need with only the model number. He won't part out a carb, but he will sell the the whole thing at what a consider a very reasonable price. Thanks a bunch for the suggestions.
