problem is now that it's drained it's tank of fuel, all of it's gone out onto the ground through that overflow pipe, dunno if it makes much difference but the fuel tap is supposedly switched off.....
Was in some random out of the way place in tipp, near the glen of aherlow, price i cant remember, wasnt me that bought it

You'd need to find out if the fuel is leaking from the drain pipe coming from the bottom of the carb or it could be from the water drain on the fuel tank.

If its coming from the bottom of the carb , its probably a little bit of rust from the tank holding the float valve open ( it works the same as the tank above the toilet )

If its coming from the fuel tank drain ( the pipe passes internally up to the fuel filler cap, to drain away rain/excess/spilled fuel) , it may have broken away internally.

Its important to fix it properly whatever is causing it , fuel is slippery on tyres.

Thanks bushy. very helpful. It appears to be comin from what im almost certain is a pipe off the carb, or attached to the carb... well near it anyway. there's a bigger pipe which is rubber, and a small plastic one coated with rubber, and it's the small one. they both exit in the same place.
Yeah i'd imagine fuel on the tyres would be bad, but at moment the main concern is that it won't hold fuel because it all comes out throught that. all of it, within about an hour it emptied half a tank.

Could it be to do woth the fuel tap as well if it wanst one of those two options? the fuel tap is in the position where it says closed, but i dunno if can trust it

The fuel tap may be worn at this stage and letting fuel past it in any position , anyway the carb should be able to hold it back.

The quickest way to get a definite answer is to remove the bowl from the carb. You can usually do this by just getting the carb out of the rubbers and pulling it to one side

** Be careful though, somewhere around there is a small pipe that feeds oil to the engine, it will be connected to the side of the carb or the rubber on the engine side of the carb or somewhere nearby , if you damage/cut it the engine will seize and die.

Anyway, use a good screwdriver ( screws will be tight) and get off the bowl and see whats living in the bottom.

If the bowl has bits of corroded metal in it , the fuel tank is rusting on the inside , you will need to remove the tank , remove the petrol tap and flush as much crap as you can.
(You can get a sealer for the inside of the tank to stop the crap in its tracks).

Have a go at that much and post back.
