Ignition problem? I'm sure this happens when there is too much advance or retard but I can't remember which one causes it!

wierd!

runs ok till it gets warm then its fucked
i left it running for about 30 seconds and it just stalls and white smoke billows out my induction kit! then it wont start.

im seriously pissed off.
i took it to get the gear box changed and there was nothing wrong with it, now ive got it back it does this, ive refused to pay them

running rich for sure.

Open the throttle and I'll bet it stinks of fuel.

Check the coolant temp sensor is plugged in or that they haven't trapped the wires between the block and box.

tried all that

how do i test if the coil pack is working?
theres no spark now, nothing from the leads, nothing from the coil to the distributer, how do i test if there power going to the coil?

had a fort , when they changed the gearbox they didnt change the sensor on the flywheel, so i changed that , but thats not the prob ,

loads of fuel going through just no spark?????????
