Before I fitted the new head (gratis from Doc) I was having smokey starts. I removed the injectors, cleaned them out but fitted new copper fire washers before torquing them down.
No more smoke ....at all !!
Surely over-fuelling will help starting rather than hinder? I'm thinking of my tractor, no glowplugs and ancient in-line injector pump, on which to aid cold starting there is an 'excess fuel button' which when pressed basically massively overfuels the engine causing it (when it eventually fires) to scream into life with clouds and clouds of black smoke.Bx Bandit wrote:Get your timing sorted first mate, really do. You kicked out a lot of black stuff when you left off at Vannys which means you're over fuelling a lot which ain't gonna help your starting issues either.

The earlier (than yours or mine) versions of Bosch pumps had timing advance devices, to give the fuel that little bit longer to ignite. But, with the development of glow plugs that don't self destruct if left on for more than 15 seconds, things changed. So instead of a timing advance, the relay kept the glow plugs on for up to 3 minutes after starting.door wrecker wrote:And diesels seem to knock more when they're cold - is that purely down to the fact that they usually (always?) have some sort of timing advance?
