You need to find or make a drip tube and use it correctly, it's not
all that hard. You and cheat with some clear plastic tubing if you
cannot find a drip tube.
Remove the #1 injector line, remove the pressure valve holder and
pressure valve. Replace the pressure valve holder. This is to allow
you to see when the plunger covers the feed port in the sleeve inside
the pump. Attach the drip tube or clear plastic line to the injector
line fitting. Aim the drip tube off the side of the pump and be
prepared for the fuel that will run out.
wire the throttle linkage wide open and operate the manual lift pump
to pressurize the feed chamber in the IP while rotating the engine by
hand. Fuel should flow freely from the drip tube until you reach 26
degress on the compression stroke, at which point it should abruply
cease or greatly diminish. This is the point at which the feed
orifice in the sleeve is covered by the plunger and fuel pressure in
the IP set should start rising toward injection pressure.
This is the best method to determine if you have pump timing correct.
Rotate the pump slightly get obtain the flow reduction at 26 degrees
before top dead center on the compression stroke of #1.
Once you get the injection timing correct, you will know if you have a
pump problem or not. It doesn't take more than a tooth off on the
sleeve that connects the IP to the timing device to result in a poorly
running engine.
good luck!
