  I do feel so sorry for @Mally... Once again @Mallykindly drove over here, with hopes of getting the MGB GT going...

And it did go...

  Momentarily before living up to it's old name of c#@t... One day I may take pity on it and call it Tim 😒🤣😂

 

Thank you again @Mallyfor popping over, honestly I am ever so grateful... 🤞🏽for the rotor motor🤞🏽😬

 

Blocked idle jet? 😁(worked for me last time🤞) Nice to see it progressing for you anyway and looks like @Mally has the required magic MG hands - good man!

I fitted new condenser and points, cleaned the float bowls, and it started first go, revved and ticked over.

Then when we were going for the test run, it wouldn't start again. Sometimes not firing, sometimes half running but like a bag of spanners.

Fitted a second condenser as I bought 2 just in case, suspected the clip on bit maybe shorting on the backplate, so bent it a bit, still the same. Prefer the nut fastening myself.

Then it hit me Rotor arm.

My theory is it starts fine when cold, you run it a while and switch off. The rotor arm warms up and starts sparking anywhere and every where. I've had it before, but it has DD stamped on and looked* fine, I meant to buy one but didn't.

There is play in the dizzy shaft which won't help.

Tried to buy a rotor arm locally, but met with blank stares apart from 1 guy who definitely had one but couldn't find it.

So retired defeated.

Have ordered a rotor arm from simonbbc, delivered to @Mrs Spart, with clear* instructions on how to fit it.

This should arrive Monday.

Theory is, if it works, she has mended it, if it fails it saves me a 3-1/2 hour round trip just o fit a rotor arm.

In the event of failure my next suggestion is a new dizzy, probably electronic.

Is this any good? https://www.ebay.co.uk/itm/112777317927?epid=5010156908&hash=item1a420d4e27:g:P5YAAOSwZW5aEYpk

Of course then I'd need to find my multimeter and timing light.

Neither of which I've seen since we stopped racing Pintos many years ago.

It's been stood 7 years, I suspect it may have been abandoned because it failed to start. Rotor arms make you feel like that.

If repro (Indian / Chinese made) then the experience of many is that they start out ok but they start to loose timing. My cheap 45d started loosing it badly after only 800 miles.

  Seems to work so far... 🤞🏽🤞🏽

  Just turned "Tim" (still think C#@t a better name 🤣) off whilst I pop out and post Giles' memorial ash key rings off to his old friends in Dorset (he likes to keep me busy 😉👍🏽)

  Will return home in a moment and see if the MG will start again... If so, off for a Service 👍🏽🤞🏽🤞🏽

So...

Got home....

And....

It works still! *phew!* 

Nice one @Mallylooks like it was the motor arm 👍🏽😊👍🏽

Drove it around the Village, seems to be over revving and the dashboard counter a tad hit and miss... 

But plan is im going to hopefully take it 10miles down the road for a Service this Wednes plus get the brake pads done 👍🏽

Thank you again @Mally🥰👍🏽😊

So the guy doing the service and front brakes called up... "Bring it over" he says!😀

 

  It started again, first time @Mally🥲!!!

  So happy, yet saddening to know that @spartacusisn't here to witness this.

  10 (very cautious!) miles later I drove it to the garage... For a Service and new front brakes.

 

  Thank you @Mally! I am so so SO over the f#cking moon with this... To know that C@#t (aka "Tim") is home AND working is unbelievable, I only wish that @spartacuswas here to witness this. 

(BTW Doug was dead impressed it was all down to the motor arm... Well spotted @Mally👌🏽👍🏽)

My revcounter does that at times and has done for decades.

A tap on the glass gets it working again.

Rotor arms are a common fault on these, but it had a 'Distributer Doctor' rotor arm already  fitted.

These are supposedly fool proof, and fooled this fool at first.

Eagle eyed amongst you will notice the black tape I stuck on a battery clamp.

The car has 2 + ve battery leads, a left over from x2,  6v battery conversion.  A little disconcerting until you follow the lead back.

Get your mechanic to put a -ve terminal on. Also needs a bit of tape round the wire near the blue connector  in the first photo.

I did it the first time, but obviously not later.

 Well done in fitting the battery and rotor arm.

Yes, for quite a number of years there was a large number of cheaply produced rotor arms floating about. It was the period when plenty cheapness Chinese parts flooded the spares market. My Dad still bangs on about these crap rotor arms as they left him at the side of the road on a couple of occasions. So shite were they that he had a small collection of new rotor arms in the glovebox of his B roadster as he knew they would fail. From memory I think they developed hairline cracks which where very hard to spot. Anyway, after enough time demand for something decent and not just cheap that failed quickly enabled the production of rotor arms that lasted longer than about 800 miles.
