Zhills (Zephyr Hills?) - agree that most people can learn by trying. It's also a lot of fun to pile on the kudos to folks like Mark who did so and give us a look at the results.
Until recently I never had a gun that was crappy enough to risk ruining, but that was OK enough that it might be redeemed as a potentially good shooter. I now have one, bought for $50 + $25 for a new base pin. Initially I was interested only in getting the rust off, but now I think I'll tear it apart and see what happens.
The first time I disassembled and rebuilt a carburetor, the results were not impressive. Had two tiny pieces left over - never a good thing.
