The Classic Marque

I'm reminded that the Italians, at least some, had trouble with the SU carb tuning and as a result Weber produced a single choke side-draught carb which was a direct replacement for the SU HS1, I don't know whether they did them for the larger versions. I've only ever seen 2 and those were fitted to a frogeye that came over for an International Healey celebration some years back. The frogeye was f...

Les,

You said the carbs were not a pair and he 'tweeked' them.
Worth checking both pistons drop at the same speed with a nice clunk onto the bridge. Miss matched springs, dampers ?

It wont alter anything but just eliminate a variable.

I had a snap ring like that. The transmission was supposed to be overhauled, and the bungler not only lost the ring but also broke a piece out of the mounting point. Luckily, I still had a replacement for the remote.

Will wait and see how it is after going back to R E Performance in Bury on Wednesday.
Don’t really want to fiddle with it myself just yet in case I cock it up prior to going to Mathewsons live end of next week.
As it is it’s drivable but just not right.

I googled the Borg & Beck part number for a clutch release bearing, earlier.

The result was that this particular part fits MGA & MGB, as well as Sprite Mk2, 3 and 4, when they actually use five different bearings.

The misinformation was lifted directly from an eBay listing that I had been looking at.

Fortunately, another result pointed me in the right direction and I was ab...

I don't know if those links are the same but su, and the later Burlen site, did a very detailed step by step guide for setting up and tuning these carbs. And specific for the different applications.

But do follow the process through as the instructions. It's very easy to dip into doing adjustments out of sequence or as a one off and it doesn't work out so well.

Email address now removed, wish getting my car tuned properly was that easy.
I wonder if Mike knows anything about tuning SU’s!

I rarely digress from original fittings, however replacing the original round section retaining ring with a 'modern' Circlip makes for a far easier fit up.
