Re: 1936 Austin Ruby Misfire

Nick, The fuel is new in the tank is only a month old.
I will check the jets in the carb.
As far as the distributor is concerned, it does have a slackness to it, in certain positions, do you think it could be that, thats causing the problem?


Re: 1936 Austin Ruby Misfire

Not sure what you mean by 'slackness'. There are several bits of the dizzy that can wear/misbehave but a sudden occurence of a misfire would suggest something has broken/given up the ghost.

Could for example be a crack/short in the baseplate. That's why I suggested a swap if you can find or borrow a known good one.

You could also try running the car when it is getting dark and having a jolly good look round the ignition system. That can sometimes reveal a short sparking somewhere it shouldn't.

Great minds think alike! A friend of mine had a misfire on his Austin K7 lorry. We ran it up in the dark and it was easy to see there was a short in one of the HT leads. They had screw on ends. Re-did the end connection and all was well. It took us a couple of hundred miles around Normandy and few tanks of fuel to finally get rid of the sticking brake problem though.

Apologies, it was a K6, as can be seen here:

I hope you get it sorted. I would still look at the rotor arm, particularly if its a riveted one, as it could be showing early signs of failure.

Re: 1936 Austin Ruby Misfire

Nick, Slackness i was referring to was the fact the rotor arm can be twisted back and forth as if the drive gear is a bit worn.

I will try running it in the dark to look for any sign of external sparks.

Thnak you for the advice on the rotor arm, I did fit a new one, when I replaced the distributor cap..
