Reducing fuel pressure at pump

[james_stan]

Hi All

Checked back but I can't find teh post which says how much pressure you
can back-off at the pump with each additional gasket (0.25mm approx). Can anyone remember ?

I'm trying to get rid of teh over-rich smell on my ICTs. Idle jet is already reduced..

Cheers

you need to check co reading on emmision tester,might be to lean ,that will cause high hc and make exhaust smell(or over advanced ign timing)

Hi

Timing is good but plug colour is black on idling so suspect high pressure maybe to blame.
will pack out pump anyway as trial and error measure.

Get a pressure regulator mate, will cost abit more but will be accurate.
