Mike, the OMC carburetor kit is P/N 439071. Ebay is a good source for one. Look for best price and free shipping. Avoid the Chinese aftermarket kits and stick with the OMC one. The aftermarket kits are less expensive, but I wouldn’t even want one for free. They have a multitude of issues.
The rebuild is relatively simple. There should be a how-to video on You Tube. Please use proper sized wrenches on the tiny bronze compression fittings on the fuel lines.
Once apart, soak all parts in your choice of carburetor cleaner overnight, then clean and rinse with fresh water, blow out all passageways with compressed air, and reassemble.
There is plenty of help here, so please ask.
