Idling

[fay66]

Easy fix... it was just a case of fitting a new fuel filter and blowing through the idle jet. Purring sweetly now. 

Given only 400 miles on this filter, does this imply something nasty in the fuel tank? Maybe worth draining/inspecting to see what comes out etc?

Sounds like the time to fit a filter king with the glass bowl!

Where in the fuel system did you fit yours? In the boot at the fuel pump end, or in the engine bay? Not sure about the wisdom of a glass bowl protecting my engine from a steady supply of combustible liquid. I have an uprated electric fuel pump mounted in my boot under a metal box so it would be quite safe in there. Do you recall which model of "Filter King" you fitted Brian?

Mine is fitted in the engine bay, and it's a VERY Thick Glass, never had a problem in the nearly 10 years it's been fitted (July 2004) but it doesn't half stop the muck getting to the carbs, cleaned mine out a couple of weeks ago and checked the filters at the carbs, nothing had got past the filter King.

Agree about Filter King. Had one from day 1 (ie from 1981) on B10 sitting 6 inches from radiator and had no problems - heat-wise of rubbish-wise. Am now putting one on the Hands.
See my comments on Sport fuel problem and do not rely on 50p in-line plastic filters as I had 3 (one in main fuel line and another 1 before each carb) and still ended up with a clogged pair of carbs.

Been looking into the Filter King variants that you suggest. One question, I can't find anything in the manual about the sort of fuel pressure that the Flavia Solex carb should be operating with and the Filter King appears to allow variance from 1.5 - 5 psi. Has anyone any advice on what it should be set to?

If it helps I have set mine on my 1600HF to 1.5psi, never had a problem.

Never touched or checked  the pressure on my filter King, it was fitted as received and it was bought for the filter function to overcome the amount of rubbish from the tank, I didn't try draining the tank as I had visions of the drain plug boss tearing loose, something I didn't wish to contemplate.
Having been over the Alps & the Pyrenees  the set pressure has never proved to be a problem.

I forgot to mention that I am using an electric  facet blue top pump, with the filter king.
