Pump to carburettor pipe - leaking

Post by Mabel Morris »

Been having starting issues. Noticed there's a steady drip from the pipe/hose that connects between the fuel pump and the carb. Think the rubber has perished beneath the metal braiding (see photo).
Would this contribute to starting problems even though the fuel is getting to the float chamber?

(Btw a new pipe from ESM is on order)

No it shouldn't do.

You can actually start the engine with the top off the carb and the right level of fuel in the float chamber.

It just stops when the fuel level drops unless you pour more in.

It is however possible that bits of perished pipe have got in, but it sounds like you have already confirmed you are getting fuel in the float bowl.

It is worth checking the jet is clear and the fuel does get to the engine though for the same reason.

It could possibly be that the petrol is coming from the float chamber overflow (there's a hole behind the little plate where the hose fits on), a high level in there may give you starting problems. Take the lid off and check the float valve is clear an that the float itself is actually floating and hasn't sunk or stuck down.

You could try giving the float chamber a good clonk with the handle of a screw driver. Sometimes that's all it takes to seat the float valve.
