That's not good...

 

All the fuel should be going down the carb under vacuum, so even if you have leaks in the carb/manifold it shouldn't give rise to fumes.

 

So, either its running rich and you can smell unburnt fuel from the exhaust, in which case it will use more than 8L/100km and the soot will carbon up the cylinders and cause over-run....

 

or you have a fuel leak from a pipe before the carb that lets liquid fuel/fumes out.

 

How's the carbon filter setup?? Still all connected? I think that is meant to be under negative pressure when the motor is running so fumes shouldn't escape, but I wonder if it bleeds fumes while driving if its not connected to the carb.

 

 

Mine smells of raw fuel when I turn it off in the garage, and I assume that means the charcoal in the canister is saturated and can't absorb any more.

[rolla rookie =D]

the charcoal canister has one hose coming off it leading towards the tank and theres another fitting coming off it going into the air. is that meant to go to the carby or something?

 

i think there is a lil bit ov a leak coming from the top seal ov the carb but its not really that bad.

 

cheers for the help -jake

Yes, it should go to the carb.

 

I think it works like this- When the car sits in the sun the fuel in the tank evaporates and vents through the canister to the carb. The charcoal absorbs the fuel on the way to stop the air pollution. When you start the car it sucks air through the canister and draws the fuel off the charcoal and burns it.

 

If the hose is not connected to the carb you should smell petrol in the garage on a hot day.
