.

Remove the float bowl and take a pic of the main jet and float pivot pin area. Its when these areas corrode, thats the real killer

Brother,you wouldn't believe how crusty some carbs can get and yet can be made usable again with some brushes,torch-tip cleaners,solvent and elbow grease.


I just overhauled my uncle's portable generator that his idiot stepson left sitting out in the rain all summer and fall full of E10 fuel.That carburetor inside was just a mass of corrosion-I had to pull the inlet needle out with sidecutters.I was able to completely clean it using the items mentioned above and it ran perfectly.Engine was a Chinese copy of a Honda GX-200.Those carbs are a bit more forgiving than Tecumseh's in my opinion,but you get the point.

The lower dark spot is a void. Looks like it goes all the way across and would let air in. Hard to believe it would seal properly.

I find it challenging to find ways to bring parts back to life.

I would sand on a thick piece of metal, use JB Weld, file and sand again using Emory cloth, maybe a flap disk would work the best, then make my own gasket using a thicker piece of cardboard.

JB Weld was my thought too, if there really is a void connecting one area all the way to another. I confess I can't see where the void is from the picture.

But you'd just need to obstruct the leak. There's no pressure involved, really, so just anything to fill up and seal the opening should do it. I would not use silicone, it does not handle gas. But JB Weld is OK with gas, once it's dried.

I think I'd do the smoothing by hand, rather than using a flap disk on a grinder, personally. Take too much off, or accidentally grind a gouge into the sealing surface, and you've just created another problem. You could smooth the JB Weld until it's just a little bit taller than the surface, before it hardens. That would reduce the amount of sanding you'd have to do.
