small vaccum hoses

Does anyone have a picture of a stock engine with the small black plastic vaccum hoses behind the carb. I have some hoses broken there. I think they have to do with thermac system. They run by the deceleration valve and thermac system behind the carb and into the carb at two spots. They snap really easily. I don't know what they do but my car misses and the thermac system doesn't work. These symptoms might not have anything to do with the lines at all.

Thanks

I think the Chilton's manual for your car (the little cheezy $8 one) has vacuum line diagrams for the carb. If you can't find one, I'll see if I can dig up my "freebie", and scan in a vacuum line diagram.
