The new solenoid has arrived and I'm expecting great things for 56 pounds... On reflection the return spring seems a bit snappier so fingers crossed.

Well...slight improvement as I could actually drive the poor thing out for a quick spin round the workshops (2 laps it was raining) and I managed to manoeuvre the car back through a very tight entrance so definitely better. However still has a huge flat spot when coming back onto the throttle so I have sent of for a gasket/overhaul kit and will have a butchers at the carb next.

After stripping the carb down the only problem I could find was a rather ucky emulsion tube...I can't recall seeing one like this with corrosion eating into the surface. Any way it has all been cleaned up new gaskets, diaphragms, needle valve etc etc. It is back on the car correctly torqued down and just needs connecting up tomorrow.

Well...one step forward two back. Started the car but it was running like the proverbial bag of chisels and a little nagging doubt sauntered in and starting whispering 'did you even bother to check that new solenoid???' so out it came put 12v across it from my battery charger and the damned thing never moved. So question is does the solenoid sit in the carb fully extended or does it rest up against the casting putting a bit of pressure on the spring and helping it to operate. The reason for this if you push the end of the plunger in a little bit the solenoid will work but when it was on the car I expected to hear it click as you turned the ignition on and off but silence reigned. So when testing back to back with the old one the old one could be made to operate a lot easier than the new one so back in it went. After about 5 minutes warming up by acting on the throttle stop and mixture screw I managed to get the little beast ticking over but as soon as you try to give it some more revs it stalls so a bit of progress. If it is dry tomorrow I will get the car outside as the fumes were a bit much inside.

My first guess would be acceleration pump membrane.  after it has been running, and you operate the throttle, you should see petrol being squirted into the venturi (with air filter off)

My experience of the fuel cut off solenoid is that it makes the car either run or not run. It doesn't make it run rough.

Hi all
I changed the 2 diaphragms that came with the service kit so I will check the accelerator pump...the solenoid thing seems to be that with the throttle stop screwed right in the car will start but run rough. With the old solenoid back in a tap on the side of the carb with the ignition on and the car starts and as I said I could get it to tickover but I'm guessing with the 'new' one in it wont start at all.

I had so much trouble with these solenoids back in the day I sold the car.... Now I would fix it!

also check the accelerator pump jet, it's a thin piece of pipe that gets easily blocked.

Hi all
The 'old' solenoid seems to have fully recovered and works like a charm as you can here it clicking on and off with the ignition being switched on and off Hmmm. Good call on this as the accelerator pump is sucking and squeezing petrol but none is coming out of the jet in the venturi will have a play tomorrow.

Hi all
Using a single strand of copper wire in a cable I managed to clear the obstruction in the accelerator jet so the carb is back on and a quick test fire showed it was working...might get chance tomorrow to give the little darling a few laps of the workshop site and see if that dreadful flat spot has gone. There is a chap in the next unit who tunes cars I just wonder if he will be able to stick his exhaust analyser up the Y10's pipe and we could set the mixture properly.

Just a thought but I am not convinced about the cut off solenoid so will put the new one in and check the lead as it is fed off the dim dip circuitry and as this is not working two birds with one stone...

Hmmm...must learn to read wiring diagrams properly the dim dip and cut off solenoid are not fed from the same 12v feed so I'll leave the dim dip for another day. Anyway got the carb all back together pulled the choke out and varoom 1st turn of the key. So we let it warm up and eventually it would tick over and the massive flat spot has gone (well done Dikappa) but it won't rev clean and is a bit hesitant. I can report it is nearly driveable and no longer stalls every time you let the clutch out so some progress. I managed to obtain an exploded diagram of the carb and it shows what looks like an emulsion tube for the idle jet? this did not come out when I was overhauling it so I will check a) it is still there and b) the state it is in

Hi all
Managed to source a spare emulsion tube  (thanks Frank) and with it fitted the car will rev cleaner higher up but still has a dreadful flat spot and started to stall again. I will check the float level tomorrow before I get the thrashing stick out.
