I replaced this broken carb top for a guy a few weeks ago.
I didn't figure it was much good, was going to scrap it, but the
more it sat here the more I thought it might be worth trying to
fix since other than the broken shaft seal bore it was in good shape.
So I cleaned it up really well and found a shouldered bolt with the same
diameter as the seat bore (.001 over actually) and did some test fitting.
I hunted around and found a couple of washers to fit flush with
the face and let the shoulder JUST bottom in the bore, then coated
the shoulder and washer with grease to act as a release agent
making sure not to get any on the carb itself.
Next I packed the area in between with Quick Steel epoxy and
smoothed it as best I could with a damp screw driver blade.
Some light sanding, primer and paint. It's not perfect, but it
looked Ok, so I put the gasket and retainer in. I figured it
might crack when I drove the retainer in, but it didn't.
I'll put it on one of my tractors and run it to see how long it lasts.
I sure can't recommend it as a permanent repair, but it
just might get someone by until they find a replacement.
