Hey guys, im in the process of tuning my weber, and got told to check the plugs to see if its lean or rich, Number 1 and 2 plugs are white, and the 3 and 4 plugs are really really black. What that meann??

Helpp.

Brandon.

what carby or carbies are you running

Just a 32/36 dgav, its out of tune big time, im getting T.A.S Performance to tune the weber on Tuesday. :D but stil why are 2 plugs black and 2 white?

Most likley -
A. leaking manifold gasket - check manifold to head bolts are tight, or
B. leads/plugs shot for 3/4

Brandon, Howd u go with the webber mate? Jst interested to see what size jets they put in it, thinkin mine needs a tune to.

So i put smaller in, and still not good, so i need to get different sized idle jets and air correcters, Im taking is to TAS on Tuesday so Im just gunna let them figure out all the jetting. Sorry i couldnt help.
