Hello, I'm currently running an old Carter AVS on my '73 360 I'm an '83 Prospector. I have a Thermoquad I had rebuilt for it originally, but couldn't get it to run quite right. The AVS runs good, but I have to use a manual choke which I don't like. The TQ has the auto choke on it still. My problem is that the spring for the secondary air valve is screwed (I'm thinking that was my problem). Without it, the air valve just flops about. I've searched high and low and can't find one anywhere. Does anyone know where I could get one? I can't even find a junk parts TQ around here.

 

Does this help any https://buy.walkerproducts.com/carbu...omponents.html

Thanks for the reply! I did come across them during my serch, but they appear to have everything but the spring I need.
