Triumph GT6 Stromberg CDSEs running rich, any solutions?
I've just purchased a triumph gt6 MK3 and I'm having issues with it running too rich. In an attempt to rectify this, I bought a colour tune sparkplug, a flow meter and the adjustment tool (all the gear no idea!). No matter how much I lean the mixture, the combustion remains a rich yellow/orange colour until the engine begins to struggle.
Other symptoms have been hesitation while accelerating, backfires at higher RPMs, lots of black liquid spitting out of the exhausts and inability to idle when warm.
Does anyone have an idea what I could look at to rectify this? Could this be something to do with the floats perhaps? Cheers.
