Hey All,

I just bought a 73 Clubman and it was running great for the first hour, then lost vaccum pressure about 5 minutes from home. Typical. Luckily i got it home I have removed the carby, cleaned it out, replaced the gaskets and well the feul pump works great. But now for some reason the car starts okay, but then runs for 2-3 seconds before stalling. Can anyone tell me why this is happening? I wanna try and get it fixed quick.

What other signs are there? Black smoke? Running rough? What do the plugs look like? Are they clean? What about the points?

Was running beautifully until l lost vaccum pressure ... distributing, sparks ect all look good .... no smoke at all .... not excess oil loss

Air filter ? Dash pot oil?

i had a similar problem with mine, if the
carby for some reason has been replaced with
a pollution one (dont now why it would
as yours wouldn't have pollution gear) then there
is an extra tube comming off the top of the
fuel bowl on teh side. if that is plugged up,
then the car stops. sometimes in the outside lane
on paramatta road in peak hour traffic.

it won't run because it does not have legs

seriously though, how do you know it has lost vacuum?

does it have a dodgy PCV (positive Crankase Ventilation) valve? unsure if they were fitted to 73 model

i had a problem with the needle valve sticking to the seat in the float bowl once, it ran until the float bowl was empty then stopped.

dicky fuel pump?

Fuel Pump is electric and relatively new, have tested it a number of times and works great,
Ill try checking the other things mentioned and get back to you
Thanx guys

Oh Yeah i know im loosing vaccum, because it has a vaccum guage

The vacuum gauge measures the vacuum in the inlet manifold.

So lets think this through,

Why is there vacuum in the manifold?
1) Because the motor is running!
2) Because the motor suck air!
3) Because the throttle is closed!

Why does it lose vacuum when you press the pedal?
Because the throttle is open!

All cars lose vacuum when you press the throttle!

Hey check to power wire to the coil I have had that cause a simular fault.

also check that the float bowl need is not sticking by removed the top and see if you can blow air through it with the float fully down then push the float up and see if you can blow any air through it.

What Is It



A Bloody Mini

1970 Mini K, 1380cc, 1.75 HIF SU, 30 70 Cam, 2" Zorts
1969 Mini K, Stock Standard and Orginal. (Slow as Hell)

Thankyou heaps for your replies. I had another look inside the carby quickly and realised that there was little fuel residue inside. After some fiddling around, I realised that the feul would only flow through the jet bearing when it was tilted on a 45 degree angle. I think this is the problem. Can anyone tell me why it does this? An how do i fix it?

Anyone?

Needle valve and/or seat could be stuffed - I didn't think my old ones looked worn until you compare to new ones. Try some new ones and set up the float properly. If you want, send me a PM and I'll send you a SU carb service manual by email - (best if you have cable )
