Engine Problems

["Andrei Cular" <acular1@xxxx>]

Ok I have finally reached the point of fustration that I am going to ask for
help.

I got a D that has been sitting outside unprotected and untouched for 7
years. The first thing I did to the engine was pull the plugs and put
Marvil oil in all the cylinders, drain the oil and overfilled it with motor
oil/ diesel misture. I pulled the gas tank, cleaned it installed a new pump,
screen, and new boot. I cleaned all the injectors, pressure regulator,
replaced the filter, and rebuilt the fuel distributor, even after everyone
told me not to. After a week I drained the oil again and this time refilled
it with just motor oil to the proper level, and added more Marvil to the
cylinders. I pulled the starter and started to turn the eninge over by
hand.after several hours under the car making sure everyting was free I put
the starter on and just let the eninge turn over and over and over.... So
everyting seamed to be ok I had oil pressure, good compression in all
cylinders, good spark, and good spray pattern from all the injectors. The
car started right up.

My problem is that it would not accelerate. When I would hit the gas it
would just bogg down and eventually stall unless I pushed the air sensor
plate down by hand. I thought it was the pressure regulator so I changed
it, no luck. After pulling the system apart again I found the injectors
were clogged, so I cleaned them again. Still with no luck I went and got a
rebuilt distrobution block thinking that maybe I screwed up the orginal when
I rebuilt it. Now it wont even start, all the injectors are clean and get
fuel. The only way I can get the car to run is by rigging the cold start
valve to be always open, and I realy dont like doing that but it the engine
will run and rev up with no load just fine. As soon as I try to drive it
with the cold start valve on I have no acceleration and can only get to
about 2400 rpm.

The only part of the fuel system that I have not replaced or cleaned out is
the accumlator. But I blew air and carborator cleaner backwards throught the
line from the engine to the tank, so I assumed that it was not plugged.
Does any one have any ideas as to what I could check? I have good spark,
the timing is at 13deg @idle the advance works just fine.


Thanks in advance.
