Did the Wolseley 1100 have the same engine spec' as the MG ?, ie. 12G295 and twin SU's ?.

Think it may have been a single carb...

I'm sure my '67 Wolseley I owned in the early '90s had a single HS4 carb, but I maybe mistaken as the Wolseley did not have the Cooper type air cleaner.

But if you look at the brochures on this link it shows twin carbs

Thanks. The photos I've seen do show twin carbs but with a central cylindrical filter box, not like the cooper so at a quick glance you might think it to be a single carb.

Robin,

The Wolseley 1100 was first produced in September 1965 and had the identical engine and gearbox as the MG / Riley Kestrel and Vanden Plas 1100 with twin carburettor application. The 1098cc Wolseley engine had the 12G295 cylinder head and high compression pistons and AEA630 camshaft that can be identified by two rings near to the large bearing journal end of the shaft. This is the same camshaft as the 998 Mini Cooper. This block is identical to the Mini 998 engine, just a change of crankshaft and pistons. The very early MG 1100 engine of 1962 had a cross-drilled crankshaft and used the 997 Cooper camshaft which has one ring and is a fantastic cam. This early MG 1100 engine had the 12G206 cylinder head which had retained the standard inlet valve size, however it benefited from improved porting and inlet manifold locating rings for the twin carburettors.

Hope this is helpful.

Alan

Thanks Alan,
I was looking at a nice original Mk1 Wolseley but it was too high an asking price for me unfortunately

That's great info Alan. I have just dismantled my MG1100 engine/transmission to refresh. I believe it is an early MG1100 engine as it has the 206 head with larger valves (used on the 998 Cooper?), 5 ring pistons (which are +20 so not original) and a TWO ring camshaft. Unfortunately, the engine was a "period" upgrade to my 1960 Mk 1 mini 850 and is missing its engine number so I have no way of guessing its age. As for the transmission...3.1FD, rubber drive joints replaced with nylon, roller bearing units, magic wand shifter.....the guy who modified it knew his stuff but the problem is that a full tear down is needed to find out what was done.

I always find that taking apart these old cars is a bit like industrial archeology or even more like the Forrest Gump quote "life is like a box of chocolates - you never know what you are going to get".

...I should also mention that my car is left hand drive and I believe the MG1100 had a single HS4 SU carb - at least here in the US, though mine had been fitted with a nice aftermarket intake and exhaust headers to squeeze it into the mini

As far as I was aware even US-spec MG cars always had twin SU HS2 carbs., certainly confirmed by all the literature I have....the only time a single carb appeared on an ADO16 MG was when a 1300 automatic was specified.
