Now now you two - play nicely!
I was always told (for Morris minor anyway) that starting from cold usually required choke and a dab on the throttle
Not complaining about the inside of the car Chris - for all the rot you removed it was relatively clean. I thought I would give her a dust and then take her to the Russian hand car wash (I was just looking for something to do and my wheelchair hadn't recharged from the morning's shopping trip so I couldn't go out in that) Once I had it clean, I was then going to try and persuade Her Ladyship I was well enough recovered from my trip in a brand new van to Kircaldy on Friday, to drive to Eden Camp, Thwarted with that before I even started. Women closing ranks against me I suppose.
Most of the stress was caused by the modern electronics on that van requiring set procedures for starting, which I wasn't used to, and the damn engine stopping every time we were stationary, which is not much good in heavy traffic around Edinburgh when waiting for a small gap in the traffic to fit into

It's one of those things I've always done. I suppose, really, I don't even know that I do it!
It's absolutely throwing it down in Yeadon, so I'm probably having a better time in the garage than I would be at Eden camp.
Chris.

Managed to divert Madam into car park from where I parked the Merc following lunch. Told her which pedal to press and ...... nothing matter with cable. Rubbish in the carb/fuel line then 
Job for the big Orange Toolbox tomorrow. Just pleased it didn't gum up whilst I was doing 70 up the motorway
Don't feel picked on David - am sure we all start cars through habit and not 'by the book' As long as it starts, no worries. Same can't be said for that VW van I had on Friday. Unless you did EXACTLY what was expected, it just wouldn't even turn over, never mind start

Maybe worth fitting an in-line fuel filter to stop the rubbish getting into the carb? I guess the float chamber may also benefit from a clean out. Actually now I have engaged the brain (as difficult as starting your car )it may make sense to open the throttle a little when cranking from cold using choke. Although there is no accelerator carb pump action, as the engine cranks it would raise the piston slightly but this should be damped and provide a temporary richer mixture in theory and less resistance to the flow through the manifold. My earlier comment that the mixture would weaken by opening the butterfly is probably only true if the spring is weak or the damper requires oil. regards David ;Rubbish in the carb/fuel line then

Actually the piston had jammed. 5 minutes from Tool Box arriving to leaving. Most important thing was he was able to push the car away from the wall so he could lift the bonnet

Do you mean the carb piston?

Yes David, the piston was firmly attached to the dashpot. At least the guy was of an age where he served his apprenticeship on what he calls 'real cars' so knew exactly what he was doing. No idea how it stuck though, as the car behaved perfectly all the way back from Yeadon, and that was only 10 days previously

You were very lucky to have a true old fashioned mechanic. Sounds as though you need to take the chamber off and clean the inside and piston with carb cleaner. Then check that the needle is properly centred if you can manage to reach across the engine to prevent a recurrence. Maybe when it is hot there is a little more clearance / it's less sticky so it ran from Yeadon without a problem. regards David Yes David, the piston was firmly attached to the dashpot.

RAC guy did all of that - highly efficient bloke. he didn't remove the carb, just sprayed and cleaned inside with it in situ. Piston and dashpot were cleaned (with carb cleaner) in the back of his van.

Sounds like an odd one. Perhaps it's been sticking on and off for a while, most noticably at 2pm on Sundays?
Chris.

Can't be that Chris. Car started fine with it stuck, it just wasn't able to go anywhere!

Dave I had a similar problem last year. Turned out to be muck in the pipe from the bottom of the float chamber and muck in the float chamber. Mine would start and idle but die when accelerator pressed. Basicly muck was stopping the flow of fuel through. |

More evidence to suggest an inline fuel filter next to the carb would be a good idea? David Can't be that Chris. Car started fine with it stuck, it just wasn't able to go anywhere!

Snoopy - that's what I thought the problem was. That pipe is a bottleneck. I always carry pipe cleaners in the boot for such purposes. Never had a carb piston stick before
David - I have loads of in line fuel filters in a box (bought a job lot at a show) All I have to do now is find the things. I have a storage area allocated to me in an unused part of the development, which started off storing car parts so easy to find. Then a change of flat meant household stuff was piled in there as well, so the car things could now be anywhere (removal men involved, unsupervised) I can't even find a nest of tables taken there by mistake, let alone a box of filters
