Carburetor Enrichment Curcuit
Written by tommikebanks14 on 10/12/2010 at 11:12 pm

To anyone who knows about the carburetor enrichment curicut on the PC800. I
have determined that the on my Pacific Coast, when the choke is engaged on cold
start I am drawing in air for the carb enrichment (larger hole at the top of the
inlet) but no extra fuel. So where is the enrichment jet? There are 3 pick-ups
in the float chamber- primary, secondary and a third- which I would assume is
for the enrichment- however it is not slotted. So is the unslotted pick-up for
the enrichment and can it be cleaned? If not, where does the enrichment get
fuel? Again- your help is much appreciated. Tom

    Tom, As I understand the carburetor design on the PC, the enrichment circuit - activated by the pull of the choke cable - pulls a blunt "pin" out of its cavity so additional fuel is allowed to flow to an orifice behind the butte

      Mission accomplished! Yes indeed- the unslotted jet is the enrichment jet and in both carbs that jet was plugged. The key was to use piano wire to unclog it. Now my bike cold starts easily. After many hours of struggle- trial and error,
