both the original carb and the new in the box carb leaked out of the bowl drain hole… what I did is wrapped pipe tap around the threads of the drain screw, but also self threaded a short screw with Permatex Seal+Lock thread compound and added a small rubber O ring… that worked… after sealing up every threaded hole in the New Carb… I found that the “factory sealed” Fuel Bowl Plug screw is leaking and I think the Main Adjustment Screw Gland bowl threads are also possibly leaking… I’ve got to take it apart again… this makes like the 5th time I’ve installed and removed it because it keeps leaking.. I did put in that synthetic fuel like as getting the copper line lined up every time was becoming a pain… you can go to a hardware store and get copper tubing, and the round brass seal plugs and new crew caps, the yellow synthetic tubing that you can see fuel flow and tubing clamps… I could have just cut my original copper fuel like but I wanted to save it for authenticity if I ever sold the motor.

Here is a photo of the threaded screw I used to plug the drain hole… I kind of thought putting a nut on would give it more surface area but it made the screw sit to low and hit the face plate when trying to re-attach it… first image is before I found out I needed a rubber O ring… but you have to cut the screw really short as to not interfere with the actual drain plug…. I also took a short piece of pipe tape and folded it in 3rds lengthwise and put one wrap basically on every threaded screw I thought might be or could leak… LOL… the motor runs fine… I’m think their machining tolerances SUCKED…
