The other day the cossie starting popping and banging quite badly,so started to investagate what was going on and found that when i took number 2 lead off it was ok but obviously running lumpy but when it went back pop pop bang, now do you think this is my problem and what causes it???

 

You need a new dis cap, maybe it had moved slightly and the rotta arm was catching . only a few ££

 

I already have one on order but is it common someone did say to me that his use to go quite a bit????

 

cant say its happened to me !! look at the clips either side what hold the cap on and make sure there ok

 

Funny you say that as 1 of them was a little slack????but i bent it a bit now so it will be tighter?

 

Isn't that just good old fashioned arc marks in the cap?

 

As andypen says, it shows tracking marks, so either physical damage to the cap or moisture has got in, not uncommon.
The arm goes nowhere near that far out, the presence of any apparent burn marks on the posts is ok, and does not affect performance.
Doing little trips or just starting up every now and again will cause condensation to form on the inside of the cap, I stopped this happening on mine by drilling the holes out a bit bigger underneath, there are four holes on the underside for "breathing", so I just drilled them out whilst my dizzy was apart.

Buy a wasted spark kit and chuck the old stuff in the bin.

 

Should be ok, should be a tight fit

 

Where's your carbon electrode gone?

 

Lol i was sitting here playing with it then it popped out so dont worry (not that you are)lol

 

er, any bloke that says that on an open car forum will give me cause to worry
