Leyland P76 Owners 2004

Question

Hi folks,
Most of us will know that the V8 was fitted with the A2 carby up to about Feb/Mar 1974, after which the Factory substituted the A6, the changes in the latter being larger idle tubes and smaller .051 main jets (instead of the .052 jets in the A2) in an endeavour to reduce fuel consumption.
I thought that was it, until now, that is all there was. I have a A1 in my possession which I always presumed was probably for another make of car, but I have been informed that the A1 was also a V8 P76 carby that was fitted to some early manual transmission cars.
Can anybody list the applications and differences between the A1, A2, and A6 carbys, and if possible, give a reason for the changes?

Answer

HI Mike.
Can you let me know how you identify the A part of the carb(A2 or A6) on the carb.
The reason for this is that I have a NOS WW which seems identical to the P76 carb but has the idle mixture screws (ie 1975 spec) plugged with tiny welch plugs.
I have noticed these on HZ 253 carbs and the Carter 2bbl Ford XB 302 1975 model year only also had them. AS I
havnt got my car running yet I have re fitted the 1/74 supplied manual carb to get the car up and running then will try the new one on it.
On my 10/74 v8 super v8 Auto matic (that James now owns) I am quite sure that it had the butterfly tube connected and this car (even though the previous owner had changed the jets to the v8 manual type )ones, or was it 186 "s" holden sized ones .
Any way this car used to only get about 16 MPG around town but on the run back from camberra on the hume streached the countey MPG figure to 21 and went way harder to an equivalent Targa that I owned (both fitted with PS) which only had 107,000klms on it when i bought it.
Both these cars also had operational Auto chokes working as per
factory spec.
Cheers
Nick
