Just for the petrol heads

Triple throat Webers, rather uncommon. Lamborghini used them on some of their V12 engines.
I wonder where else they may heve been used.

Quite impressive exhaust manifolds too!

I'm glad I don't have to work on it.

"Faaark". Triple throat down draft webers. You would have to search Australia for a Weber guy or go to Italy to get em tuned. Most Weber guys are in old people homes. I had triple 45m webers on my EH 179 back in 68 and a guy at Bert Jones Racing would tune em..

IIRC Chris Amon's V12 Ferrari sports car that was out here in the late 1960's used the triple throat Weber's,they switched back and forth from fuel injection when it had its run at Warwick Farm.

SU had a rare twin throat model,scarce as hen's teeth and go for huge money these days.
There was a pair on Oz Ebay early 2000's,around A$500 and no one bid,still kicking myself 25 years later for not buying them.

I had triple strombergs on a Holden 202 years ago.

Everyone always said "Arent they hard to tune?" and "Dont they always go out of tune?", but it was pretty straightforward to get right and they worked well without going wrong.

Just had to adjust the idle screws and the linkages to make sure the same airflow was going through each carby at idle and with a few revs and they were fine.

I got a little tool to do the measuring of the airflow and figured it out from there.

I had dual SUs on a Mini years ago and they never stayed synchronised for ver long. I ended up buying a Lynx manifold and fitting a twin choke Nikki carbie from a Datsun.
Win/win; slightly better fuel economy* and improved pickup throught the gears.

Later I had Datsun 180B SSS with dual Hitachi (constant depression SU type) carburettors and they never ever needed adjustment.

*Fuel economy was not that good for a 1 litre Mini but the engine was far from standard. Would pull over 7,000 rpm in top gear with a long run up (a bit above legal speed limit I believe!)

I bought and sold a couple of Mini's with dual SU's in the 1970's but as you say were a problem but easy to sell to enthusiasts.
Weber was the go,BMC had it as a Tuning part so just bolt on.

Jap SU's were good,as were the Jap. Solex's.

I named my daughter Nikki, after these.
No, my son is not named Stromberg or Weber etc.

A friend of mine called his son Cleveland after the Ford engine. I told him a good thing he is not a fan of Buicks otherwise the kid would have been named "Nailhead".

Buick V8 "Nailheads", produced between 1953 and 1966

How long did it take to recover from the kick in the nuts?

Haha, she as too young to kick that high when she found out.
