[Mg-t] leaking carbs

[peter-thiel at sbcglobal.net]

Hi Herb,

   You don't mention what car you're dealing with, but Blair is correct, 
it's probably dirt or corrosion in the needle and seat assembly. But it 
could be the float isn't floating. If you're sure the fuel is coming from 
the overflow pipe(s), the next two suggestions can be skipped. Perhaps the 
banjo bolt is not tight on the feed line. I've also had the cover bolt of 
the float bowl loosen up and then the gasket doesn't seal.
    Fuel overflow happens to my '53 TD often when it sits a while. When I 
turn the key off and on a few times, this often stops the flow, as the pump 
is turned off and on at the same time. Otherwise I raise the hood (bonnet), 
and with the key on, tap the offending float bowl with the handle of a 
screwdriver and the flow stops almost immediately. (I have an airy barn that 
the smell of gas doesn't bother me if it gets around. If you're in a garage 
attached to the house, you may think differently.) When the car starts, the 
vibration usually stops the flow also.
    As far as Grose Jets, here we go again. This has been discussed here 
several times with plenty of votes pro and con. Personally, I find the stock 
needle and seat work just fine, and grose jets are just as prone to the 
overflow problem, or maybe more so.

Best, Pete Thiel
         1953 MG TD
