This may seem like a dumb question, but did you put the leads back on the right way??
Yeah, I think you are right with this one, I even tried swapping the leads on that one Coil pack just in case, but still the exact same problem.
Is the plug from cyl 4 wet with fuel when you pull it out? Did you break the insulator when you took it out or put it in? Is the plug cross threaded?
Funnily enuf, the spark plug was not wet.
I Changed all the plugs, as the Original ones were Black and sooty (Carbs running very rich), and after many times of cranking and idling, the plug on the miss firing cyl looks brand new ??
I cant see it being fuel somehow...:oo1:
I would have to agree with you, but I think I have tried almost everything in terms of Ignition, so this is the only other thing that I think could go wrong ???
The coil pack could still be buggered - I've heard of Commodores losing one ignition output from one of the the dual packs.
- This is a very good point, I havent tried swapping the coil packs yet, to see if maybe one is faulty, but I will give this a go next ! (Fingers crossed)
pull the ignition lead a small amount from the sparkplug,creating a small gap. This in fact causes a better spark in the plug. Worth a try to see if the faulty cylinder fires.
Gave this one a go as well, Still the same problem, but you can definitely here the sparks coming from the boot to either the rocker cover, or plug ! (Wasnt doing this before I replaced the Ignition lead and Boot !)
Hmmmmm - Im am now wondering if it is a Fuel problem ?
I have some very small fuel filters fitted, and they seem fine, I even tried blowing air through them just to make sure that they were still flowing - They seem fine.
Is it possible/common that the Needles/Venturi can get clogged with crap ????
A friend said that I should try some carb cleaner, and rev the Sh!t out of it, to try and dislodge any possible crap ????
I might also give this a go tommorow !
Again, thankyou for all your help !
Im a little peeved that I had this trouble sooo soon, as I only got to ride the bike for 400 odd Kays, (6 Days total). And it has been off the road almost longer than it has been on !
