Right, here comes silly question...

Are you getting fuel to the system, empty tank ? is there a blockage in the fuel pipe / carb... When you took the plug out, was it wet with fuel ?

There should be fuel in tank, was around a quater full today before college.

Plugs are wet, so cant see there been a blockage in the carb.

OK, start w/ the basics like Guessworks was suggesting. The plugs being wet indicates that you have fuel... too much fuel or spark at the wrong time so the fuel isn't getting burned.

You said you "got the firing order sorted"... why did you even question it? Just to make sure we're on the same page, standing at the front of the car looking at the dizzy in the block, firing order is 1-3-4-2 going counterclockwise. Plug #1 is to your "right" near thermostat and #4 is to your left, towards the clutch. Generally, the rotor under the dizzy cap will have the #1 spark plug wire on the dizzy cap near the 1:00 o'clock position.

Remove the plugs and let them dry. Do NOT wire brush them to clean them. While the plugs are drying recharge the battery (if you can) and start checking the static ignition settings. Assuming you have points, check they are in good shape and opening properly when you turn the motor over by hand. Check their gap (or dwell if you have a dwell meter). Make sure the gap is right before going further. Once the gap is set, pull out your Haynes manual and set the static timing for your engine. Once you've done this you'll have an ignition system you know is set properly.

That leaves fuel. A full tank doesn't mean you have fuel if the pump isn't working. Also, if the float valves in the carb(s) are misbehaving, the float bowls can overfill and put too much fuel in the engine. Lastly, a misbehaving choke linkage, or failure to release the choke at the right time can flood the engine.

Forgive me if you've got an injected Mini where little of this applies. However, the basics are the same. You have to have fuel and spark at the right time to run. Check each system independently and make sure it's basic settings are correct and working, along the way you'll find the problem and sort it out.

i removed the dizzy cap and all ht leads, thats y i questioned it. The plugs and firing order is correct.

The battery is flat and i have no way of charging it at the moment. All we can do is try bump start it, and hope it works.

Nothing has changed.
Could the earth lead have any effect too, it looks really crappy?

Again, if there is spark and fuel (but not too much or too little fuel) then it probably is timing related. This all assumes things were OK before. Sorry, but since you don't have power in the battery it will be almost impossible to troubleshoot at the moment.

In general, when a car sputters to a stop loosing power along the way it's generally fuel related. Sudden death of an engine (without explosive noises and obvious mechanical clanks) usually means an ignition problem.

was spluttering, but that may be due to a very very mucky air filter. I've got a cone filter, i will get fitted if the engine isnt dead :S

You got all that fixed for under $40? Fantastic! What do you mean "got a replaced dizzy"? Rebuilt? Used? Re-adjusted? Regardless, I'm glad it's sorted out.

a 2nd hand unit from another engine. it was less then 2months old, he built the engine for someone and they had broken something, so he was stripping it.

Clutch slave changed with a 2nd hand one from the above, dizzy changed, points n timing set up etc, £20. :angry:

I changed coil other day and forgot to fasten it bk on right, drove over a bump outside college and car cut out, wouldnt start....blocked both lanes because i wa turning into car park, a guy pushed me, i popped bonnet and a wire had come off, doh.

Other then that, running fine except a headlight as gone. :S

is it only my car that doesn't seem affected by the damp? I haven't got an ignition guard or anything, yet it starts first turn every morning, and can go through deep puddles without a trace of a misfire, drive behind a lorry in driving rain getting covered in spray all day long, anything like that! Am I just lucky? I know the electronic igntion helps with a stronger spark but I can't imagine it would make that much difference.

mine never really had a problem till monday morning. i could do all u say and then it just went.... :angry: but its all fixed.

I guess its damp or a short in a wire which has caused headlight to go off.
