Barry, never whacked the tong on it but it had a 16amp fuse and never blew
its like the choke element after bout 20secs or so its to hot to touch
my car was a real pig in winter if i turned it off
liveable in summer but the flat spot when u take off or stomp the gas was a pain and something alot of upright motors seem to suffer from
my old solex even did it till i unclogged the heat risers

The IMDU ( Inlet Manifold De-icing Unit ),suitable for air cooled Buses and Beetles, is a revolutionary product that is sweeping the world. Regardless of whether you suffer from icing or not, the neck of your manifold always runs at a cooler temperature, and will not give optimum performance. The IMDU alleviates this by regulating it's own temperature & uses a current of only 1.8 amps (equivalent to a side-lamp bulb). It fits most 1200cc to 1600cc air-cooled engines in 6v or 12v form as well as an extra-long type for vehicles with twin choke Webers
