    Is it an early air cooled motor? If so it should have thermastatic louvers to control the amount of air that passes over the motor. The carb should allready have heat risers off the manifold to pre heat it.

    If you have a stock fan shroud it will have those louvers. They aren't as pretty, but work a lot better in heat and cold. If you have dual carbs it gets tricky for heat risers, but not impossible. If you have an external oil cooler you may think about covering it too. Good luck, hope you get it figured out....And try to stay warm yourself

    here is a link to a downloadable VW manual in pdf format. WORKSHOP_MANUAL_-_VOLSKWA5.pdf

    the bellows are visible in the cut view of the motor. The file size is about 45 megs.

    What configuration of carb are you running? Is it a single on the stock intake manifold? Are you having problems with the intake manifold icing over?

    I had this problem with my street buggy and the only cure was to either run the exhaust back up through the bottom of the intake to prevent icing or to pull carb intake air from a heated air source. Stock bugs have a hose that draws hot air up from the air that exits the cylinder area.

    Another thing is do run a dual carb setup. The carbs are attached to the head by a short manifold so they don't ice over.

    I heard that you can run the oil lines up around the carb to keep it from icing up. Never seen the setup so I don't have detailed info.
    All you got to do is remember 2 thing, Mentum and Mo-Mentum.

    Odyknuck wrote "The carb should allready have heat risers off the manifold to pre heat it."

    The heat riser that Odyknuck is referring to is incorporated into bottom of the single carb intake manifold. There is a tube that runs along the bottom of the intake manifold that is attached to the exhaust manifold in two places. The tube is designed to move exhaust gasses through one end of the tube then along the bottom of the intake manifold runner and exits out the opposite end. The gasses flowing through the lower manifold heating tube keeps the intake manifold from icing over in cold weather. The tube works well when the stock VW exhaust system is used but works poorly then an aftermarket exhaust is used.

    The reason for this is that the exit of the intake heating tube exits deep inside the stock VW muffler basically at the muffler exit which creates a vacuum in this tube drawing exhaust gasses through it. If you are not running the stock muffler the exhaust gasses do not flow all of the way through the tube. The gasses just kind of move in and out of each side where it is attached to the exhaust header.
