Morris Minor Owners Club

Hi there. Just a quick question incase someone out there can help.
I have a 67 minor that will not restart when the engine is up to running temperature. Bit of a bind when you stop to re-fuel lol.
Any suggestions as to a cure would be grately received.

Likely to be a fuel over flowing problem. Try holding the throttle wide open while you crank it. Does the petrol pump 'tick' steadily when you switch on the ignition? If so - indicates that the needle valve in the carb float chamber is worn - and is allowing fuel to flow through even when the bowl is full. Doesn't matter when cold - it wants extra fuel then, or when running because it can use up the fuel. Probably a new needle vlave will solve the problem - cheap and easy!

Thanks for your advice. Much appreciated

The test is - does the fuel pump tick constantly ? It should tick once or twice when you switch on - but should then be silent.

No, there was no ticking when the ignition was switched on. Does this denote a fuel pump problem?

No - that's quite normal really, well - after the initial couple of ticks! Hmm - may simply be that the fuel level is set too high - although it's not really adjustable on these later carbs. Has this non-starting when hot thing happened just once - or several times?

Is the choke closing fully when you push the knob in? Push the centre of the carb jet upwards and there should be no movement.

Only happened the once so far!!

Oh well - may be just a one-off. Next time it happens - foot flat to the floor - don't pump it - and crank it!

Thanks guys
