    Carburator

    Hi Guys. A friend of mine has a broken carb. (Cast is broken) It's a Holley and I believe it's on an 80s crusader, but could be wrong about that. Who is a good reputable carb company to purchase an appropriate rebuilt from? Thanks

    Sound deadening

    Good morning. What are you all using for sound deadening material under the doghouse? Motor is fairly close, so a bit of heat. In a perfect world, something self adhesive would be great, but I don't want it to continually fall off. Anyone use a product they are happy with? Thanks Dave
