Joe Curto in the US charges $300 USD to completely rebuild a set of SU's.
They might as well be new when he's done. You might want to keep that as an
option. The down side is that the shipping airmail could be expensive, and
you're talking at least a month downtime between shipping and his working on
them. He might be willing to send over a pair of HS4 carb bodies with new
shafts, and a rebuild kit if you return your used carb bodies. I would
expect that option to be cheaper. I seem to remember someone else doing
that with him from Australia a few years back on the MGS list. Let me know
and I'll find his number.

Subject: Which carbs
Hi every one...
Have been enjoying the late afternoon sun here in england in the car!
But have some niggles which although I don't plan to sort out until the
winter I would like to start thinking about.
Firstly my dual HS4 SU are knackered, 150K miles of abuses have taken
there toll.
So I was wondering.
1)Should I rebuild them (including new jet bearings to fix the sticking
jets and new bushes to fix the throttle spindle air leaks.)?
2)Should I pay someone who knows what they are doing to rebuild them
(150 Pounds +)?
3)Should I shell out for new ones (300 pounds+)?
4)should I switch to a single Webber (? pounds) but lower maintainance?
5)Should I switch to dual weber (increased overdraft)?
Also the power of my stock 1500 seems to die at 4000 revs, Is this
normal, or is this another sign of a worn carb and or distrubtor. I
thought I might install an Aldon Ignitor exlectronic system anyway!
Thanks for the help
the summer has been too short!
Cheers
Tim
