You should be able to find a used one. There are getting to be tons of used Phazer parts around. Will probably have to buy the pair. Tried eBay?
What is wrong with yours?
I have a set I will sell you. Are you looking for just the carb body or do you need all the jets and stuff to go with it? I have everything but the carbs are striped right now. $35+ shipping stripped. Or $45 + shipping back together.
Thanks for the replies everyone. I got very lucky, it turns out I thought that one of the pilot jet holes was stripped out. Took it to my service guy and he said it was fine. Just needed the jets cleaned.
