Well... Now my brakes are back to almost normal, I can return to this. I have booked an MOT for Thursday - to see if it'll pass emissions, but should it fail (it still has that odd misfire) I still have a few ideas, before I rebuild the motor.
It could be some of the following so I am looking for advice on how to test these in the best way possible ideally without £400 smoke machines or emissions testers.
Spark Plugs - I am going to take them out and get pictures of each one, one by one, to compare them and see if there is too much fuel / not enough / oil and or coolant etc
HT Leads - This I am not sure how to test without simply replacing them. - but may be worth cleaning the ground attached to the gearbox as that is connected through to the HT leads...?
Distributor cap - I am sure this won't be the issue - Because I replaced it about a year ago now, though I suppose I have been green-laning / off roading a few times since so it is possible dirt or debris got in there? I will go in and take a look.
Rotor arm - Again I think this is unlikely as like the previous one I replaced this about 12 months ago... But I am sure I will look into that when taking the dizzy cap off.
Distributor shaft play - Will check again.
Wiring & grounds - As mentioned I will probably remove the gearbox ground and some other grounds I can find to clean them and try again.
Vacuum lines - I will spray all the vacuum lines I can find with brake clean to see if I can find a leak (increase of revs).
If anyone has anything else I can check, please let me know before I spend ~£1500 on an motor rebuild as realistically I don't want to do that soon, eventually though
