Hello Tony,
the fact that your engine is stalling after you have driven a couple of miles can be caused also by a failing rotor. A lot of rotors which suffer of bad quality are on the market so if you have changed your rotor by such a bad one in the past chances are big that this rotor is failing. The right one to use is a red rotor which you can buy for instance at the distributor doctor. It is always best to replace rotor and cap at the same time.
The problem with this bad rotors occur as soon as the engine is warmed up and after cooling down alle seems to be okay again.
At least you can try this out by borrowing a good rotor plus cap from a fellow Rapier owner.
Regards,
Peter |

Here we go again!!
Had the same trouble with the IIIA last week. Came to a stop in a long queue at traffic lights and the engine just died. I'd done about 20 miles, of which 3 were on the motorway about 10 minutes before it happened.
Fortunately I managed to get down a side street by using 1st gear and the starter. 30 mins later it started again as though there hadn't been a problem!! I'd put new points in a few days before, and cleaned the plugs, so perhaps it was fuel vaporisation again? So I searched the Internet (basically as I'm not savvy) and found this:-

Are there any heat shields available for the twin Zeniths on my car?
Failing this, has anyone got a paper template to make one as I attend a classic car restoration nightschool and will be able to reproduce such a shield from a pattern.
Tony. |

Thanks Glenn,
I'll burn a couple of gallons off and then do as you suggest, but will wait for another dry salt-free day!

Hi Tony,
Not sure what VSP is - some sort of additive? I personally would not use additive, just a decent 97-98 octane fuel Shell Optimax, or V-Power as they call it now - that's 98 minimum the Esso & BP ones are 97. As for poor starting it could be you've picked up some poor fuel: I try to avoid supermarket stuff as quality in my opinion is variable & the only time I've had trouble is when I've used Tesco.
I would not say your octane rating is too high & even if it was, it should not have the effect you describe. Assume car ran OK other than the re-start after you fuelled up? Could be another problem that's coincidence?? I'd try to run some fuel off and add a few more gallons of decent stuff, albeit I appreciate your reluctance of getting stranded with same problem. Just my thoughts, but sure there will be more advice shortly  |

I've had trouble in the past with my Series IIIA when trying to restart the car when the engine is hot.
Since then I had Hometune to it to sort it out, and it's run and started very well ever since until:-
Last week (Christmas 2011) I filled up with a different make of petrol and put the usual amount of VSP+ in the tank for a fill-up of 20 litres. I only topped-up with 17 litres of petrol rather than the 20 litres I usually put in.
I gave the old girl a non-stop run of about 25 miles just to get everything moving and came up to the garage door. The garage door key is on the same keyring as the ignition key, so I turned off the engine, unlocked the garage door and tried to restart the car. It wouldn't start, so I left it for half an hour, and went back to it when it reluctantly started and I was able to get it into the garage.
My question is - will there be too high an octane rating in the tank because I didn't put the correct amount of petrol in for the measured amount of VSP+, and will that have caused the car to run hot compromising the restart?
I'm loathe to use it again in case I'm stranded somewhere far from home if I turn the engine off.

Poor starting when hot.
