Larry,
Get the SU video tapes from Ztherapy. 4 hours of everything you want to
know. If pictures are worth a thousand words, video is worth 100 times
still pictures.

Description from the website:
" JUST SU'S "
British HS6 and Hitachi "SU"
This is a reshoot of the very popular " 240Z-280ZX TuneUp" video! PN# ZTV09
Why did we redo it? Four years of manufacturing the SU to better than new.
Sponsoring and supplying race car teams. Campaigning our own test car in
the Sports Car Club of America. Answering tech questions at the National Z
Car Convention and the Motorsport Auto West Coast Nationals...hundreds of
hours on the phone providing tech support to all kinds of crazy engine
builders/owners/tuners with SU's and nitrous, SU's and turbos, SU's and
13:1 compression, SU's with the vent tubes capped, SU's with the fuel line
hooked to the vent tube, 48mm 240Z SU's on bored/stroked 1600 Roadster
engines with funky linkage**510 owners with home market 38mm Z/2L shaped SU
carbs/Volvo 1.8-2.0 owners with funky spring-loaded throttle shafts...it
goes on and on and on and on and on....
This instructional video is about 4 hours long. All hard core SU. No fluff.
Watch it twice. I don't repeat myself.
Some of the topics:
* The most intimate parts of the SU carb-the float and how it sets the fuel
mix**Grose Jets, and why they help prevent engine fires**Stacking the mix
nut spring for perfect fuel distro**Which mechanical fuel pump flows the
best**The correct way to set the needles (leave the ruler in your
desk)**64-71 4 screw nozzle alignment**3 screw offset nozzles, and how to
avoid using them**Cutting down the pistons and polishing for best air
velocity**Which oil do I use in the dashpot? My O2 sensors say 20W50 gives
the best accelerator pump action???***Dyno footage of the carb guts from
Chet Wittel Racing-see the air/fuel mix split the butterfly!**Total air
flow potential for the SU, and why 3.1 litre strokers can use 2Litre SU
carbs**6 barrel SU 48mm on a 240Z done, why?**Dumping DGV Webers, the
cracked exhaust manifold and exploded muffler. Installing SU's as Nippon
intended**260Z conversions, and the adapters that allow the factory air
cleaner to be used**Passing visual smog with SU's on a 7/72+ 260Z (oops, I
meant to say a 240/260Z)**Cold air box from TWM Induction**Throttle shaft
and choke linkage removal and install**Choke-on idle speed adjust**High
speed balance**Piston drop test, or how to flow your carbs for a perfect
match**New Remanufactured ZTherapy SU Carb install/tuning from
A-Z**ZTherapy TuneUp kit install, and slamming the other "TuneUp kits" for
being so incomplete**Air horns, and who is making them better than
OEM**Yes, there are insulator gaskets available for cheap!**All four heat
shields**Firewall rods for 260Z conversions**Getting max throttle out of
your monkey-motion throttle system**Why Nissan OEM nozzles stick**Side load
tension adjusting for the choke linkage**Needle charts, Nissan part
numbers**O2 sensors and why you need EGT as well**Fluid dynamics, Carb
Cleaner 101, and lots of other trivial trash to enlighten you day. Coverage
of the HS6 1 3/4" British SU, the nozzle alignment, choke linkage, air
horns, unique variations between the spring loaded throttle shafts, piston
drop tests, smaller Brit carbs and Stromburg hate mail. Heavy on the Volvo
HS6, because we do more of this 1 3/4" SU than any other.
If you don't like it, send it back for a refund.
20 bucks for the tapes (4 hours spanning 2 VHS tapes). Or, if you can
tolerate Extended Play mode, get the $15 single tape (4 hrs stretched via
EP mode)
Sincerely,
Dave Driemeier
