I notice you do not have a fuel filter installed. Fit one of the
cheap transparent plastic filters (still the best) in a visible
place in the fuel line to the carbs. Debris from the fuel tank may
have stuck a float valve and blocked a jet or a gauze filter
somewhere.Kees Oudesluijs

About 4 years ago I rebuilt my HD8
carbs and the car has run great since then with no
adjustments required or made.I put the car away for the winter in
about November last year.
In probably mid January I decided to
take the car out. It was a gorgeous day and I had to go to
the grocery store about a mile away. I started the car and
it ran fine. I noted that the gas gauge read between empty
and =C2=BC . I started of to the store, but I noticed an obvious
smell of raw gas when I was driving. When I got to the store
lot, I parked the car, did my shopping, and came back out.=20
When I turned the key, I now noticed that the gas gauge
moved up to dead on empty whi8ch on my car means you are
really out of gas!. When I started the car, I got about 100
feet when the fuel pump started hammering. I got another
couple of feet and the car ran out of gas. Fortunately, I
was just across the street from a gas station so I took my
trusty gas can, went over and filled it, then came back and
poured it in the gas tank. The car started up fine but began
running really rough. I went another =C2=BD block into another
store, parked the car and went inside. When I came back out
about 15 minutes later there was a pool of gas, about
2-3=E2=80=99wide, under the front of the car. I started the car and
it barely ran. I literally had to coax it home. It sounded
like severe fuel starvation =E2=80=93 running barely on about 3
cyclinders.There was no more smell of raw gas
nor any fuel leak as before.When I got home, I rapped the top of
the float bowls on each carb in caser it was a stuck float
valve. and it seemed to run a lot better. I felt at that
time that a float valve had stuck and probably siphoned the
fuel out of one of float bowls through the overflow tube.Fast forward 3 mo=
nths: Last night I was getting it ready to
take it on a bit of a road trip today it and when I took it
out, it ran very poorly =E2=80=93 again like fuel starvation but
not as bad as before. It also popped back through the carbs
frequently which I interpreted to be a very lean mixture I did the follow=
ing:put another 3 or 4 gallons of gas in
the tankTook the float bowls apart and
cleaned them out =E2=80=93 there was a bit of sediment in them but
nothing worthwhile. I also checked the floats which were
both leak free. I also cleaned out the float bowl filters at
the in line.
I checked the Gros float valves and
they seemed to work properly =E2=80=93 held upside down, they closed
and opened right side up.I disconnected the fuel line at the
fuel pump and blew air back into the tank thinking that when
it ran out of gas, sediment in the bottom of the tank may
have plugged the intake. It blew fine into the tank.
I have 2 fuel pumps on the car =E2=80=93 the
regular SU and a facet pump. I pulled of the fuel line at
the float bowl and turned on the ignition. The SU pump and
the facet pump each filled a coke bottle pretty quickly. I
did not measure pressure. The gas looked clear and pure. I
do not have a fuel line filter. I checked the plugs all seemed good
and were in fact burning on the lean side.
I pulled the distributor cap and it
was nice and clean inside with no sign of carbon tracks.
I have electronic ignition so there
is nothing I can check there.I checked the timing =E2=80=93 it was right
on. No matter what I did it didn=E2=80=99t make
an improvement.I replaced the Gros float valves but
it made no difference.Today I pulled the carbs (which on a
BJ8 is no easy task) I checked the diaphrams and both were
in good condition.
Now I am stumped.
Is it a fuel problem or something else? Can any one offer
any suggestions?Brian DrabVancouver B.C.
