This is getting annoying now

The 2nd hand engine was put in - it had plugs and leads already present

So i left those in as they were better nick then mine

Anyway - Was a bad misfire alot so i replaced HT's - problem fixed for 1week
Luckily i brought the plugs at same time as leads, so fitted new plugs - problem fixed for a short while
But i still kept having a very lumpy idle and the odd spitter as i revved up

Well tonight again - the idle was massivily lumpy, but all this time - no EML indicating a misfire btw, and a loud clicking / cracking noise could be heard

driving home no issue - smooth

Pulled up - shunting into place its rough again + cracking
Get the hood up and airbox off and start examining the leads and plugs



So this is both New plugs and leads - i can see the arc'in happening

So swapped the plug lead from cyl 2 to cyl 1 - the fault is recreated there, cyl'1 has a spark appearing - cyl 2 is not

So this is a HT lead fault surly? But there brand new?

But maybe of less than exemplary quality?

I'd be inclined to return them (with a link to the video).

Me too... its on my phone, so yes it'll be coming back with me thats for sure....

Atleast its a easy job todo when the hood is up

they are better in sense they are designed for the less accessible plug to have a longer shaft to allow fitting.....

i usually find once you pull an old plug lead off these puntos they are usually scrap afterwards
your new leads are you sure you have clipped them tightly onto the spark plug top?
also is the breather pipe connected onto the airbox as it sounds like engine pulling in gasping air

Yes its gasping because the airbox wasn't attached so i could do the video
Since cyl2 is under the air box

Yea they loose there pinch so to speak, but i'll make sure again that its snug fitting
