Hello dancrim,
this is a difficult question.
I would like to give you further questions like this. What does "good shape " mean ? It can be everything.
How well is it "rebuild"... ? Is it really a healey carb ?
In all my questions, it is a risk of unkown ...
Only what you have done by yourself or by a specialist, you know what is done.
For me it sounds like "how much costs a green healey"
Try to find out how must cost a new one,compare it with a price of a professional rebuild. Nearly the difference is the the price that I would pay.
Bye- michel who has carbs that works well, with a little clearance..
