Re: Colortune

["Alecks & John Graves" <alecks@globalnet.co.uk>]

   I have used a Colourtune on both of my Triumphs. On the Spit 
with SU HS4 carbs it worked absolutely spot on. The car performed
better than ever. OTOH on  my GT6 with ZS 150CD carbs( soon to
have HS6 implants) the Colourtune is pitifully useless. I was told
that the older 2 liter engines don't run well unless they are running
rich mixtures.
