Good evening Mick , apologies if the following is a complete waist of time but do you have an advance retard system on your engine? could it be malfunctioning enough to cause your problem , all the best with the fault finding , Geoff .

Another possibility...
 

Another thing I would try is a new distributor cap and rotor arm.

Keep plugging away and you'll find it :happy:

Dire frag'ems? Nope :(
 

The suspense to know the limp-mode cure is rivalling that of the USA election result, Mick !!!

Has anyone sugested looking at the bob weights in the dizzy? My Marlin ran realy cr#p untill the springs were replaced on the bob weights. That fixed it!

Ballast resistor? Loose earth? Fuel pump filter, not allowing enough fuel through?

After the 30 second run, does the car go back to normal running after it has been turned off and then back on?

If you leave the car running on a fast idle, does it loose power after 30 seconds or is it only when being driven?

When it suffers from the lack of power, what difference do you get pulling the plug leads off one at a time?
If you take the plugs out as soon as it has a loss of power, what are they like? Clean, sooty or wet?

Blocked breather on the fuel cap?

I had a TVR once that sprayed water onto the distributor from a leaky radiator seam. I blamed the misfire on some cheap petrol bought previously. The leak wasn't apparent with the engine stopped.
I think that one of the original Crypton analyser units would solve this- they measured all sorts of engine parameters and could even diagnose single cylinder problems.
Without breathing too deeply, when in limp mode, does the exhaust smell of unburnt fuel? For a fuel delivery problem- do you have any transparent pipe, or a clear filter in the fuel line?

A blocked breather on the fuel cap wouldn't cause a vacuum after just a 30 second run but I think you are right, it is probably fuel related.
I would check the fuel pump, a weak or porous diaphragm could cause a lack of fuel. I would also try and put an airline on the fuel pipe and blow air back into the tank to make sure there isn't a blockage.
You could fit a small temporary fuel tank under the bonnet and run the car just using the throttle linkage to see if it drops power, if it doesn't I would fit a new fuel pump, they are not very expensive.

Flexi fuel pipe collapse?

Bye Bye Baby....
 

Did you ever get to the bottom of the engine cutting out ? I'm sure it must have been something silly !

Shouldn't cost much to notify your insurers of a change of vehicle, normally around £25 unless you are upgrading to a higher performance, more expensive car.

Congratulations on the sale and good luck with your first trip out in the Monaco.

It wasn't cutting out, just going into a sort of limp mode. With hindsight, I'm certain that one of the CD175's pistons was sticking. The purchaser had read the blog, so it was a warts and all sale. A man of his calibre shouldn't find sorting it a problem

It's a cheaper car with lower performance. Insurance brokers are latter day robber barons/highwaymen.

Regards, Mick

I would contest any excessive fee for a change of vehicle under those circumstances. Who are you with at the moment ? Name and shame them !!

If ever I have to transfer an insurance and I don't get a discount on the charges, I always tell the agent not to bother sending me a renewal notice at the end of the term.

Adieu Lotus
 

good news !!!

Lovely car, underappreciated but gaining followers at last.

Mick - A belated farewell to your Tribute.

I was always a big fan of how well your 'D Type' turned out. :cool:

Cheers, Paul. :)

Temptation Strikes - Again
 

Great option as a donor, go on, pry open that wallet

An interesting project ! The advert quotes just a few weekends work to complete it so you could have it on the road by the end of lock down !
Trouble is with TVR's is they usually end up off the road due to a rusty chassis so that needs to be factored in. Will that body really fit over the chassis, I thought they were quite wide cars ?

I have never seen a TVR 260/280 that had a rust free chassis.
Having owned a late 260i, the outriggers and rear suspension
tubing braces were almost corroded through. Removal of the body and close inspection will show that repairs will be needed.
Powder coated chassis tubes are not the cure all as they will rust from the inside out as well.

Surely it can't be a Xkss and a D Type ? I thought they were visually quite different ?

No where does it mention who made the body ? or am I missing something ?

Does that look like loads of aluminium sheet propped up , for the inside I assume ?

Paul

Guess who needs to read the Haynes D Type book he got for xmas :icon_redface::biggrin:

Happy Birthday To Me.
 

well why not you only live once how big was your grin?

i see the spitfires daily flying out of biggin hill i think they have 2 at the moment for paying flights

some of the others there a friend of mine sprayed up.

Congratulations Mick. On my bucket list too.

Not so extreme but at least I had the hood down.

Can't beat flying in a "proper" aeroplane, the Spitfire must have a once in a lifetime experience ! Last thing I went up in with a flying experience was Chipmonk about 40 years ago, modern planes are like going on a bus !

Yes, and a two seater Hurricane with a female pilot. Top girl.
Now I have to put my hand in my pocket again...I mentioned my 60s Chipmunk flights to 'my' pilot. He said "It's the poor man's Spitfire". This one was at Kemble in 2019'.
