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!
