Hi guys my dad has a problem with his minx, when he puts his foot down on the accelerator pedal itís stutters and coughs then finally gets going. When he pulls away it struggles, heís put new leads, plugs converted to electronic ignition, new distributor cap and many more.

Could anyone shed any light on this as heís just finished restoring it and itís really annoying him.

Adam.

Welcome to the forum.

Has the carb been overhauled? I'm not too familiar with Minxes, does it have an accelerator pump in the carb? Is there a filter inside the fuel pump that could be blocked? Does the colour of the plugs look ok when checked?

The carb has had new jets, itís been tuned by someone who does it for a living, plugs are fine and the filter isnít blocked. Heís had a look at it but now it wonít start, also heís been told that it could do with a new spindle on the carb so it might be worth changing that I guess?

Hello Adam. you need to establish whether this is a carb problem or an electrical miss.
Drive the car in such a way as to force the misfire to occur then do the same again with the choke pulled out say a quarter of its travel. Repeat with the choke pulled out half then three quarters etc. If this cures the miss or stumble you can be sure there is a carb problem. I do not know which carb you have but if it has an accelerator pump start there by checking the plunger seal and the drilling by which the bore is filled then with the motor not running whip the throttle open and see that the nozzle is squirting fuel.
Come back to us with your results.

So he has replaced the accelerator pump in the carb which seems to have cured it, still runs a bit sluggish but a lot better than what it was. He needs to replace the spindle on the carb as itís a bit loose so he think it should be fine after that, thanks for your helps guys.

Worn throttle spindle will make idle setting a bit messy but I don't think it will make much difference to general running.
