Buying a car shortly, it's been stood for possibly three years or maybe more, it starts, made it to the MoT station and passed but it's hicking and stuttering.
It's a much modded engine, we're suspecting blocked injectors, old fuel, possibly dirt in the fuel and maybe a blocked filter. Of course it could be electrical (Emerald electronics).
Assuming it is one of the fuel related problems, what are my chances of filling the tank with some new fuel and getting it home 250 miles away. Obviously, a filter isn't going to unblock but the injectors? What damage could it do running lean on one or more cylinders I wonder?
Or I could just get it recovered but that would be an extra cost to me just getting it back., money that could be spent on the car.

Do I feel lucky?

I wouldn't, if it's misfiring, surprised it passed emissions.

^^^ What 'e said.

I just wouldn't risk it without knowing a lot more about its condition.

There's no way it could pass any legit MOT if it is misfiring.

I would be surprised if injectors were a problem at only 3 years.

Fuel maybe, it would certainly do no harm to remove the old fuel, and fill with new.

But just get it and give it a check over. See if it misfires sometimes, all the time etc. Then determine if one cylinder, or all cylinders.

Of course, find out history, did it even run correctly when parked up ? Are you buying this as a total unknown ?

Find out what the emissions results were at the MOT test

It's a car from 1973, MoT not a legal requirement and emissions by visible smoke only.
Owner deceased, friend of owner selling on behalf of widow.
Huge list of mods carried out but we think it last ran, except for in and out the garage and trip to MoT a month ago, about three year ago.
Mods include conversion to injection from carbs.

Don't drive it more than a mile or two with a misfire.

Whatever is wrong is unlikely to fix itself.

Treat it as a non runner which will potentially need a new fuel system.

Don't assume it ever ran well on the new injection system unless you've seen proof.

It can destroy your engine. Melted pistons/ heads/plugs, broken rings/ring lands, head gaskets, exhaust valves, cylinder walls, con rods and bearings.

Other than that, crack on…

very unlikely on an old crusty n/a engine he's just driving a little to try and get it running.


But if he has never seen it run right, just start with basics. Hope that it might run, but equally assume it never has run correctly and start from there.

Get it recovered to a garage you trust locally, far safer that way in a long run. A few hundred pounds could easily escalate if the engine needs major work?

1973 car - been stood for three years - engine misfiring - 250 mile drive home.

I wouldn't even contemplate attempting to drive it, it can only be a recipe for disaster and a minor problem turning into a major failure.

Oh and most 'fuel' problems I've come across turn out to be ignition.

I agree, but I wouldn’t be driving 250 miles before I knew it was running right.

true, but anyone would be a bit mad to try and drive such a new purchase that distance.....

And I've been there and done it, and had many dramas along the way LOL. Except mine was laid up for a lot longer than 3 years ( this was 20 years ago ). And I was very mad to try.

Ha ha, I'm old enough to know better but I've always been one to "give it a try".

BTW, it's not a "crusty old engine" it's a bit special and I hope in good internal health. Just sat around waiting for too long.

Anyway transporter arranged, thanks for the "don't be so f---ing stupid" type comments, you're right.
I'll pass the hat around for contributions later.

In that case it's worth a bit of pampering before you put it to work. Getting it transported was a good call.

Sensible OP. You going to let us know what it is at any point?

^^^^ Wot 'e said.

Just because it is mechanically sound currently doesn't mean it will survive in the same condition after 250 miles of misfiring/detonating/lean running etc.

250 miles sounds like a decent return trip.

If the journey takes you past Northampton, I'm happy to help you push it for a bit. Maybe we could get a PH relay going scratchchin
