Hello. I have a few questions about my '75 MGB.
1. I have discovered that the PO had removed the standard SU Fuel Pump and
added a small electric pump under the hood after the fuel filter and before the
CD175 carb. I think the original pump (located on the boot kick board on the
right side ?) had some kind of pressure shut off. This non-standard pump
seems to run constantly from the time the key is in ACC to the time you switch
off.
Q: My carb is running rich, and I am rebuilding both the carb and pulling the
engine for a rebuild this weekend. Should I look at replacing this pump with
an original? If I use my handy Zenith-Stromburg tool can I keep the carb from
flooding the engine? How about float adjustment?
I notice that MOSS sells a replacement fuel pump that they say is more reliable
than the SU. I can't tell if it runs on or is pressure sensitive.
My bogus pump is new - Should I drop another $90 US and get the SU or can I fix
my fuel problem with carb ajustments?
ALSO:
Q: What is a good way to de-carbonize plugs ? (I can sand or scrape them, but
is there a cool solvent or something that removes carbon?)
Thanks all!
