Uh Ho...what may have happened here...?
Hello everyone
It was freezing here this morning. 'Scotty' started first time as ever...then after about a mile just stopped, cut out after laboring a little. Started again, then stopped (no response from the accelerator, felt like he was fuel starved or nothing at all getting to plugs... then started again. then without moving off the same thing happened again.
Then after starting once more was fine for about 5 miles. then stopped again. But after restarting <again> he has been fine for the remainder of my journey - about 20 miles.
Any ideas as I drive with a certain amount of trepidation now after that?
Cheers,
Tony

Tell us what engine, etc.
Even better - put it in your signature.

I'll change my signature now thanks.
Its a 1988 1.9 (78ps)...not sure what the '78ps' means.

Muck in the fuel, leading to blockages in the jets? Best way to tell is to take the top half of the carb off and look inside the float chamber.
Faulty choke mechanism? If the plastic link between the choke unit on the side and the choke flap is broken, then the choke flap may open and close unpredictably. Take the plastic pancake off the top of the carb and see whether the choke flap seems to be attached or free to flap about.

It's German for Pferdestärke (ps) which is Horse Power but at the wheels.

Is that correct? It's a metric unit of slightly different size from the old imperial mechanical horsepower (1PS = 735.5 Watts, 1 imperial HP = 745.7 Watts), but Wikipedia says that DIN testing still measures at the engine's output shaft. The testing procedure takes account of the standard engine configuration with water pump, alternator and exhaust all connected.
Wikipedia wrote:Deutsches Institut für Normung 70020 (DIN 70020)
DIN 70020 is a German DIN standard for measuring road vehicle horsepower. Similar to SAE net power rating, and unlike SAE gross power , DIN testing measures the engine as installed in the vehicle, with cooling system, charging system and stock exhaust system all connected. DIN 70020 is often seen abbreviated as "PS", derived from the German word for horsepower Pferdestärke. DIN hp is measured at the engine's output shaft, usually expressed in metric horsepower rather than mechanical horsepower.

Re: Uh Ho...what may have happened here...?
Stolen from the a good source.
This unit (German: Pferdestärke = horse strength) is no longer a lawful unit, but is still commonly used in Europe, South America and Japan, especially by the automotive and motorcycle industry. It was adopted throughout continental Europe with designations equivalent to the English "horse power", but mathematically different from the British unit. It is defined by the Physikalisch-Technische Bundesanstalt (PTB)[1] in Braunschweig as exactly:
1 PS = 0.9863201652997627 hp (SAE)
The PS was adopted by the Deutsches Institut für Normung (DIN) and then by the automotive industry throughout most of Europe, and is always measured at the wheels, as opposed to most factory horsepower figures, which are rated at the crank

Ok, that's the ratio of 735.5 Watts/745.7 Watts

Interesting. What's the 'good source'? That's not what Wikipedia is saying.

The source was Honest John from the Telegraph.

I think I'd trust Wikipedia in that case - if it was wrong it would have been spotted and corrected by someone who knows better - that's what I love about Wikipedia. I think the Honest John reference was just a forum post (rather than Honest John himself) and even there it was contradicted (corrected?) in the very next post.
Sorry! I'll shut up now.Dhammadad wrote:So.....my stop start issue?

Oh. Sorry. I was just expecting the usual "...I had that and it tuned our to be..." type of replies.
Are those points definitive then?
I'll have a go when I finish work.

Nope, but they're possibilities. Could be other things, e.g. related to ignition, but certainly I've had the blocked jets issue myself (muck in the fuel tank, caused by a decaying filler pipe, leading to muck in the float bowl), and I also know that the plastic choke link is a relatively common failure, since I now make replacements.
