I have just completed one, having sworn off doing it for years. However my annual bonus is due!!!!!

The instructions could be vague, mine had none at all. Fortunately the Forum has covered this many times over the years!!!

I purchased a 38DGMS manual choke and hooked it up as follows:

FUEL
Fuel supply - mechanical fuel pump to 3 way filter with tank return. Supply via Hose until I get a Tube bent. Supply to bottom of inlet.
Return pipe on carb just above the inlet - blanked off with a piece of Hose.

CABLES
Throttle cable - special kit to attach
Choke cable - special kit to attach

VACUUM
Distributor vacuum connection - manifold vacuum - port pointing up at 45 degrees just above the throttle linkage.

EGR valve vacuum connection - ported vacuum - port pointing out horizontaly at the side of the carb.

PCV connection to filter - awaiting a second hole to be drilled in the filter housing as current hole is on the wrong end.


PHOTOS
I attach some photos. My carb is oriented 180 degrees turned from most you see as it is RHD and the throttle cable comes in from the other direction over the engine. You can see in these phitos the two connections I have. firstly to manifold vacuum going back over the vave cover, and ported vacuum that heads down to the EGR valve.

You will note the choke cable was not yet installed or filter when the photos were taken.

If you have your carb correctly mounted you will find the manifold vacuum port on the bulkhead side and the ported vaccuumm connection facing the valve cover.

This helps some, thanks but I have the electric choke on mine so I think it's set up a little different?!

The electric choke model does not have a choke cable (of course) but instead has an electrical connection. This should be routed to the oil pressure switch and then on to the ignition wires (red with tracer).

The ports are the same as far as I am aware.
