Re: [mogtalk2] 4/4 Running On

I believe Colin is correct regarding possibly being a weak mixture if I remember correctly the colour of the electrodes should be a pale brown - straw - colour. But as always stand to be corrected Phil On 11/07/2012 10:11, John Mott wrote: Thanks Colin The colour was washed out by the flashlight. The ambient light meant using a slow shutter speed without the flash and my shaking hands put the pictures out of focus. Here is an out of focus picture which shows a more true colour of black. I do not think it is running lean. A couple of months ago I replaced the auto choke pull off diaphragm and freed up the fast idle cam on the twin choke webber but this should not affect the mixture.
