Carb pissing out fuel !!!!
Turbo Mini Forums

Hi just put the old turbo bak together and now it see
M to be leaking fuel out over flow and thro the manifold !!! Any ideas on what the problem could be don't know the history off the carb but can pretty mug say it's original and not been rebuilt !

There is no overflow on a turbo carb, how are the pipes connected?

it cant be connected that wrong as we got it started!
theres petrol down the back of the block, but to me it seemed like it was coming from the inlet manifold where it connects to the head!

is it possible to have fuel coming out of there if its so rich and not sealed correctly??

And there was fuel drippin at the bak into the heat shield !! Everything done up tight

There a pipe from the fuel regulator into the carb and the return onto the plenum !! Then Peter Baldwin blocked another one off think that went to solenoid might b wrong tho

what ever you do dont put the pipes on the wrong way round and fill you intercooler with fuel!

what type of fuel lines do you have, i had the old ones with fabric leek from god knows where, you think there tight but still leeking.

does it leek with just the fuel pump on or when on boost?

if you are Sure! yopu have the pipes conected right!

then the problem will lie with a stuck open float bowl valve

Yer they are correct double checked them they are all new rubber fuel pipe !! I thinking it the carb ain't been used for at least a 6 months !!! Maybe more and ain't got a clue about rebuilding them

mike we'll take it to bits tomorrow mate.

i reckon the float bowl is stuck open as steve has said. thats why it was smoking so badly, and the plugs had gone a bit black.
think we might need to check the oil as well as if it was running that rich, it may of got fuel in the oil....

Take the dashpot off and start the fuel pump, then you will know for sure.

Here now took dashpot off no fuel comin out ! Hoses are tight and correct we are confused !!!!

a sticking intermittent float bowl valve

think it must of cleared itself as it was fine once we started it up.
didnt smoke and we even got it to idle on its own!!
hopefully it will get its mot and we'll be able to go mitp in it!!
