I posted earlier about this and this should show what I am trying to fix. Pic is a little dark but you can see the weld someone has put on the block. It extends from the front where you can see it well to the back above the air cleaner to carb hose if you look closely. I'm wondering about a good fix. It is cracked right next to the weld because it looks to me like someone just welded a bead on it and didn't peen it or preheat it.
