Rough Idle - with video

Haha, I appreciate everyones input, its just I have tried upping the idle speed before. I hope it is a solvable stutter.

Did someone say "stutter"?

Divided opinion on whether to change float bowl gaskets or not.. Me personally I would change them, particularly if they are the originals as once flattened and then disturbed can be prone to weeping..

I've had my bowls off probably 4 or 5 times and they're still fine

I did say "can" and not "will"

Quick Update:


Plug caps arrived and fitted - made no difference


Also received my infra red temp gun - fantastic little toy! and indeed £8


At idle from cold it seems after 5/10 minutes that the cylinders are about 160 degrees or so at header, apart from no4 which is around 200 degrees. I haven't had time to play with the mixture on 4 to see if it would bring it into line with the rest, but I also wonder at this stage whether a partially blocked idle jet would lean it out and cause the discrepancy.


Gives me something to play with on my week off anyway.
