Other SU components in P38ny components made by SU

I wondered if there were any parts on the P38 made by SU. I had an agency job in the summer of 96, after finishing uni, taking parts from SU into the LR plant in Solihull. I always thought it was for the very last of the Classics but curiosity has got the better of me.

Who’s SU?

I worked on them in the 1970s when they first came out. Cannot recall any fitted with Strombergs. But they were both reasonably easy to tune. As far as i recall SU had a fixed needle with a jet adjustment nut on the bottom. And Stromberg a fixed jet and the needle adjuster inside the dashpot.

The SU certainly had an adjustable jet, I thought that, like the Stromberg, the needle was also adjustable. Maybe we had non standard needles on the race stuff. I always preferred the Stromberg.

Needle on SU was fixed in bottom of dashpot by a screw. and jet adjustment was a nut on a spring at the bottom as far as i recall. Stromberg had a fixed jet and a sprung adjustable needle inside the dashpot. Still have the carb balancing tools and special tool for adjusting Stromberg needle somewhere in garage.

Only thing that ever failed on the Stromberg was the diaphragm.

I have these now. “Hand me down”from dad. Used them many times as a youngster.


Not used for ages though.
