You're just trying to 'pre-oil' the cylinder walls and rings a bit
before you crank it up after sitting so long. 10-15 cc should be
more than enough. Any engine oil will work, it will just foul
the plugs slightly... maybe making it just a bit harder to fire
the first time. Shoot it in, turn it over by hand a bit just to
lube the walls. then... with the ign. coil HT lead disconnected,
crank it over a few revs to get oil pressure first. Then hook up the HT
lead and fire it up.
As far as the revs go .... check and see if your fuel filter or a badly
deteriorated fuel hose (collapses internally) is limiting fuel flow.
Also check static timing. With an electric pump, disconnect the
fuel line from the carbs and add a 3-4 foot section of hose.
Stick the hose in a gallon size container. Turn on the elec pump.
You should be able to fill the gallon container in under 5-7 minutes.
If much longer... either the fuel pump is not delivering enough fuel
or a hose is collapsed, or the filter is clogged or something
along those lines.
YMMV Good luck

Subject: Carb Problem?
Good Day List, I have a 79 MGB LE, all original, which has been garaged
last 7 years. When it was shut down, it would start, but only rev to approx.
2000 rpms, then begin to sputter. I have now rebuilt the stromberg and am
getting ready to attempt to fire it up. Before I do so, is there something
else that would cause these symptoms that I should be looking at? Also, I
have heard or read somewhere that I should inject "marvel mystery oil" into
each plug hole and let set overnite before attempting to fire it up. Is this
recommended? If so, how much oil?
Thanks and Safety Fast,
Tom
