Carb

The 1920 at Rock Auto is $117 + $30 core, so without sending in your old one, about $147. I have heard these are pretty easy carbs to rebuild, so if mine needs attention I'll probably just go that route.

I'd definitely jump on a $30 one if it was new/rebuilt. But was that a one-shot deal on ebay or do they show up regularly on ebay? Because if there's not going to be any more for $30 on ebay, then it doesn't really matter.
