how to check a radio button based on value

I'm getting a value into a variable like this:

var cur_weight=$('#weight_12').val();

The only possible values are 1, 2 and 3. Radio buttons look like this:

<input type="radio" id="weight1" class="weight" name="weight" value="1">
<input type="radio" id="weight2" class="weight" name="weight" value="2">
<input type="radio" id="weight3" class="weight" name="weight" value="3">

How can I check the right radio button based on the value matching the variable? I was trying this:

$('.weight:radio[value=cur_weight]');

...but does not seem to work. I only want one radio button checked at a time, of course. Thank you!

Excellent, that works. Although the full solution would be:

$('.weight:radio[value="'+cur_weight+'"]').attr("checked", true);

Need the attribute checked in addition to the selector, which I was also missing. Thanks!
