Pilot/Air Fuel Mixture Screw

[Sparky84]

Hi All

Has anybody used a Colortune Plug to adjust their Air Fuel Mixture to make it Just right, not too Lean and not too Rich.

Read about them, they seem alright, But are they?

I always seem to have a problem with Plugs getting fowled up and mates behind telling me its running too rich from the smell

Cheers

Pretty sure the colortune has been discussed here before.  While I don't see it causing any issues, if you follow the tuning advice in the files section - there won't really be the need to spend the $$ on it.  

Here's the post - at the end covers setting the idle mixture: http://www.fjowners.com/index.php?topic=655.0

Thanks fj1289,

I will be looking this up,

I have set it as workshop manual suggested and mixture screws are about 2 1/4 turns out and sounded and idled nice but I thought I could improve low speed city stop/start running with the ability to see inside.

I do need to do shims and properly balance carbs also as I think this will help
