948/1098 swap, which carb?

Post by jetfire88 »

I am helping my friend put a 1098 (10cc) engine in her '59 LCV. It will be a simple replacement keeping all the rest of the stock bits. She can get the 1098 for less than the cost of a re-ring of the 948.

Will the 1098 be happy with the 948 carb? If not what are the the differences between the carbs, just the needle?

We are in the US, so we don't have ready or reasonable access to later model A series parts, except via ebay, etc.
The value of our dollar sux worse than our government right now.
With the exchange rate and shipping, our cost can easily be triple what the selling price is.

I am putting a 1275 in my '58 Traveller, and I would prefer to run a single carb, but the cost of sourceing a carb, manifold, etc. from your side of the pond is not feasible for me right now, so I will freshen and use the twin Midget setup I already have.

Thanks, everyone, for all your assistance, and a Happy Christmas to ALL!

Jim

The 948 and 1098 engines both used the HS2 carb so should not be a problem. Needle spec may have been different though. I'm sure someone will know but the cost of shipping a needle shouldn't be expensive at all. http://www.burlen.co.uk/

Needle: M (standard) AH2 (rich) EB (weak)
Spring: Red

Page 13, The 1098 had
Needle: AN (standard) H6 (rich) EB (weak)

If you are running the twin carb Midget setup, check that the exhaust manifold fits the Minor exhaust system. I fitted an LCB system to mine so I have never checked the standard Midget manifold.

The 948 engine has the H2 carb - not the later/better HS2 - and the earlier inefficient manifold. However - the 1098 will run on the 948 carb - just may not give it's very best. As above - a new needle will only be buttons to post......... The 948 gearbox may not last long with a 1098 engine...... The Spridget exhaust won't fit a Minor without a bit of modification - but not impossible.
