Tin Top not revving
Not exactly locost, more lo-value.
My Dad has just become the proud owner of a M reg Metro 1.1. The car has done next to no miles in the last 5 years, and has lived outside for the
last 2. Unfortunately this was a family member's car who has now passed away after a long illness. He serviced and MOT'd it for 5 years,
and although its a Metro - its in quite good nick.
Apart from - it wont rev. It will idle, but as soon as you try to rev it, it dies, foot off the throttle - it idles again. Doesn't stall.
I haven't heard it but my Dad says its exactly like a blocked main jet in a carb engine. This is a single point injection. There are no
audible air leaks.
Any ideas? Its too good to scrap, but not good enough to spend much on.
Edit - dodgy spelling

Sounds like it could be lack of vaccuum advance - if it has one! Has the pipe become disconnected?

Sounds like distributor centrifugal weights siezed. Will idle fine but as soon as you enter the advance curve, it stalls.
Needs a strip and loads of WD40, classic laid up car fault

Hadn't even considered that. We were thinking fuel side.
Anyone know if it would have mechanical advance at that age?
Edit - Father says it looks solid state.

Just flip your dizzy cap and have a look!
Hopefully it will

The car (and my Father) are in Norwich and I am in Mansfield. So I am the medium for the problem.
I will get him to check it out, although he does know his way around a car (and a Haynes manual) so if he says its solid state it probably is.
I really appreciate your answers, and at the moment its a tow away, so ALL help is gratefully received.
Thanks, David
PS I cant provide anymore information until tomorrow evening as I would be sacked for logging on at work.

Is it on an SU carb or MEMS single point injection ?
If its an SU most like cause is the dashpot in the carb is seized, you can test this by removing the dashpot filler plug/damper and using it to lift
the piston a few mm - then release the dashpot should return under gravity with a definite "click" --- if not strip off the dashpot
cover and clean it out with carb cleaner. Refill the damper with thin engine oil (10w/40) or ATF.
If it is single point injection carefully (!) disconnect the small bore pipe between the throttle body and MEMS ECU and blow it through to clear out
the fuel trap. If that dosen't work check the throttle position sensor is connected properly and working.

if its injection,
then check other important sensors
like temp sensor?
PLugs? Bobine? etc. etc.

Check the exhaust! I inherited a Fiesta that had been stored in a garage for some years that would just about run at idle but would die when you
opened the throttle. Even though it looked almost new, the exhaust had rotted internaly and was almost completely blocked.
