Hi Would an electrical hot air blower, bolted next to my carb, heat it enough to prevent icing?? The one i have is meant to go on the dash .... it uses 10 amps (120watts). The inbuilt carb heater consumes 2 amps and basically doesn't work due to the k and n modifications (the normal pre-heat kit is in the shed). The heater can raise the temperature of an object 4 inches away by 60 centigrade within 2 minutes. Obviously if this is an alloy carb the heat would quickly "flow". (Bearing in mind the carb normally gets roasted to 100 degrees during the summer months due to its location so it shouldn't explode). You could always try running copper (i think its copper) wire round the carb and running a current through it. Its a trick i've heard of being used before on the rallying scene and definately works for iced up carbs. Can't you just splice some hose into the cooling system, and wrap it round the carb ? But when the car is cold, the water going round those pipes is cold! |

So if you wanted it to work before you even started the car - that wouldnt work |

underneath with a flaming torch trying to melt the fuel in the fuel lines
which had turned to ice.

I remember watching a vid about somehwre very cold (-20 or something like that) and a truck driver was underneath with a flaming torch trying to melt the fuel in the fuel lines which had turned to ice. |
Mainly because older derv formulations would become 'waxy' at very low
temperatures. Not frozen as such.
Of course, petrol needs _much_ lower temperatures to freeze - and carb
isicng is caused by moisture in the air freezing.

That's for a completely different reason, though. |

Does carb-icing affect things that much ? |
The cure on my ax is to use more than 3/4 throttle, thus invoking
a fuel dump into the cylinders. (Or in other words, the second flapper
opens).
This is nasty ... you go from a hesitating , coughing , wheezing, weak
mixture running engine to full bang for your bucks literally over
1 mm of throttle movement.
Serious .... 1mm, >just< enough to start to open the second choke
and *bang* you are on your way.
Accelerating though, so its .......... on/off/on/off/on all the way to
work!!!
(E.G: The only time you don't accelerate when the second choke opens is when
you are going up a 1 in 10 hill in 5th gear).
Anyway ... merry christmas.
