Hi all,
Whould one of these from evil bay suit my stock grey in my EK?
http://cgi.ebay.com.au/HOLDEN-STROMBERG ... dZViewItem
As i under stand the earlier greys were of a smaller capacity? 132Cu??
Have rekitted my carby but it still leaks fuel from the plunger shaft to linkage area. (Pisses out actually.) Have disassembled carby again and found nothing out of the orderary, just figure shes a bit worn / old, leak is stopped but for how long i dont know.
Thanks for your help.
Anthony.

Sounds like the float level in the carby is incorrectly set.
Undo all of the top carburettor body screws and carefully remove the top cover without breaking the gasket.
Fuel level is supposed to be 5/8 of an inch below the top of the carburettor main body.
Bending the float tab toward the needle valve will lower the float level and bending the tab away from the needle valve toward float will increase the fuel level.
Maybe also check for a stuck needle valve or a needle valve around the wrong way in the needle valve seat assembly.Also check that the float actually floats!! Sometimes they do leak and fill up with fuel and sink.Then the fuel will literally just pour in.
Hope that helps,
Cheers,
Terry.

I can't think what to write here so this will do.
float
also i think when you check the fuel level in the carb you need the moter running with the top off the carb. a bit scarey, but it wont blow up if you dont smoke near it. that give,s you the acurate fuel level otherwise it will be an 8th lower when turned of it is a easy fix and worth a try ..i also bought a reco carb of evilbay from melb carbys which is good but took em three or four weeks to deliver
when they start building them like that again i will buy a new car of them

Hi again Andrew,
decided to post this for others to read.
With regard to the carby's for grey's - yes the original FX-FC was a 132 cu in. engine.
As far as I can determine the carby for every grey is a BXOV-1.
The specifications according to my workshop manuals between the two I chose (FE and EK) are identical except for the float level jet (0.070" FE and 0.073" EK) I do not believe you would be able to determine which set are included with a kit although my opinion would be that they would opt for the larger one to accommodate both.
There is every chance your grey has been bored to a greater capacity - others may be able to suggest if you may need to increase the size of jets - I didn't when I put a larger grey into mine without any noticable difference.
When I mailed you concerning your fuel leak, I forgot to mention that those figures for the float level (5/8" - 11/16" below the top of the main body without gasket, with engine idling at operating temperature and on level floor) are quoted assuming you have from 3 1/2 to 4 psi of fuel delivery pressure from the fuel pump at carburettor height - I don't believe you should begin to look here for your problem - I would check the fuel level then the mating surfaces of the carby air horn/main body.
Have you re-kitted a carby before? The retaining clip to hold the fuel float pin will fling out at you so beware! You may wish to consider blocking the venturi with a soft clean cloth just in case.
You must of course replace the float level needle and seat as a pair - they are a matched set, this may be another reason your carby is flooding.
Word of warning when adjusting the float tab - don't force the float needle into its seat when bending - you'll probably damage the seal.
There may be a very slight chance your power valve is either stuck open or the vacuum piston/spring may be stuck in its lowered position.
I don't believe this would cause flooding at the location you indicate but..........
The discharge into the throat of the carby from the power valve is from the brass tube which is located in the centre of the inner venturi - I don't believe there would be sufficient volume of air down the venturi at idle to even make this possible.
The power valve should be closed with the air horn removed.
Nah - forget this whole paragraph, don't think it is going to have anything to do with flooding - running rich at above idle speeds - yes, idling - no.
Hope this helps Andrew,
mail me if you still have problems and I'll put a bit more thought into it.
frats,
