yet more troubles with 14 LD200
Now the car will not start at all! It was running well, then abit of coughing, then nothing. Looked like a blocked fuel line, so I replaced the line and fitted a vent . Nothing, so I replaced the new electronic ignition and put back the pints, plus a new coil and new condenser. Still nothing , new plugs and so on. any ideas? does anyone have a good diagram of how to wire the distributor? Could be a mistake there.

Re: yet more troubles with 14 LD200
Time to get back to basics, Keith.
1. Check fuel pump is working. Remove the float bowl and empty it.Check all the jets are clear and the accelerator pump works Put it back on and then use the manual lever on the pump to ensure it fills the bowl.
All OK? Then it must be electrical.
1. With the ignition on, ensure you have 12 volts from the "SW" terminal on the coil to earth. OK? No? Take a direct feed from the A1 terminal of the control box to the SW terminal. OK? You have a wiring fault between ignition switch and coil.
2. Check you have a spark at the points. With the ignition on, separate the points with a small screwdriver. There should be a spark. OK? then it's the high tension circuit. No@ check how the points are fitted. Make sure they are earthed from the baseplate. Ensure the condenser is OK (fit one known to work) Make sure the LT wire is making good contact with the heel of the points.
3. Check High tension. The the coil HT lead from the dizzy cap. With the ignition on, hold it 1/4 inch from the block and flash the pints. There should be a BIG spark.
4. Turn the engine over and ensure the dizzy shaft is actually revolving. No? broken skew gear or broken timing chain.
If all this seems OK, check the timing.
If that's OK, there's not an awful lot left. You could do a compression check to ensure you don't have blown head gasket.
What have I forgotten, chaps?

Re: yet more troubles with 14 LD200
That's a pretty comprehensive check list . Is the choke (cold start) mechanism working?

Re: yet more troubles with 14 LD200
everything appears to be OK. I think there is some sort of coincidence going on, first, it was fuel starvation, that has been sorted. Next I had all the ignition apart. I thought it was impossible to put the distributor 180 out? the slot is offset. It is behaving like the ignition is way out. I will have to do a timing exercise from the beginning.

Re: yet more troubles with 14 LD200
I think it is timing . How it got "untimed" I have no idea. I see the only way to get it right is take the valve cover off and get the TDC from that. But now I am going away for 2 weeks . I actually got some backfires and bangs so the sparks and fuel are there.
Re: yet more troubles with 14 LD200
Maybe you altered the timing when you was adjusting the chain. Is this possible?

Re: yet more troubles with 14 LD200
You could check for compression pressure with number one spark plug removed to avoid removing the cover but with only four bolts to undo, removing the cover is only a ten minute job to check the valves.

Re: yet more troubles with 14 LD200
Timing rarely jumps a sprocket. I should look more closely at the points, and I mean examine them very closely. Is there any burning? Is there any white deposit on them? This could indicate a condenser problem which can give exactly the symptoms you first described. I had this problem on my Daimler Fifteen. It was running perfect then, suddenly coughing stuttering, dying completely, would then restart and run at idle but as soon as you pulled away it was all over. I got out, flicked the points a few times just flicking against the spring, then it was OK for a mile then started again. The points were white and looked like a powder on them. I cleaned them put back, OK again for a while.
I then went mad, bought new coil, made new leads, fitted new plugs, new set of points and it still ran like a dog.
Put in a brand new quality condenser from The Distributor Doctor and perfect harmony was again restored.
Expensive lesson!
There are so many really rubbish condensers about nowadays.

Re: yet more troubles with 14 LD200
I have been away . Still won't start! it had electronic when it stopped, now has the old points back. I can now only think the timing is not getting set right. It half started this morning then banged and popped a lot so there is a spark and gasoline as well.
