TOYOTA MASTER PARTS FICHE 1977
I don't know why the marked part numbers are 21000 there is no reference to this in the parts catalogue, ALL carbies start with 21100 , 21000 is not allocated. .
40PHH-R Bought from API 1979.
21000-88225 Left Notch disc choke mechanism. Single screw holding cap over Jets.
40PHH-R .
21000-88232 Left ditto
21000-88233 Right ""
40PHH-T OEM Ex API 11111-88253 Yamaha Headed engine.
21000-88255 Left Bar choke lever, two screws holding cap over Jets. TOP different.
21000-88254 Right Bar choke lever, two screws holding cap over Jets. DITTO
Mikunis fitted below to my original high performance pre-pollution TOYOTA engine 18R095125 with the Toyota designed head and the small head bolts.
21000-88232 and 21000-88233 have never been separated.
40MM Mikuni-SOLEX.
Exactly as depicted in Engine rebuild book 8-21 Fuel System 18RG Carburettor SOLEX.
The choke cable is stranded wire and extends through to both carbies and is secured by screw down pressure, which eventually wrecks the cable and it shreds.
Set below are possibly an ex Celica GT? Ex API and post pollution.
Designated as 40PHH, Type T. This unit was OEM for Toyota, hence - Type T
The fuel hose clamp shows the set came from an engine with mechanical fuel pump (18RG or 18RGR/U)
Note different carbie tops with some sort of diaphragm mechanism or dash pot bleed down, suggesting later model post-pollution carbie from GU engine?
Barrels are marked 21000-88255 and 21000-88254.
The choke mechanism is different and the tops are certainly different.
Choke cable stops at Left and single aluminium bar extends across to right and is fixed to both choke bars, with the different method in activation of the manual Choke.
21000-88225 and unknown second mate.
Show at top above the unknown set for comparison.
The choke mechanism is as per the RT104 with a notched indent locator.
Venturis have been removed and the design matches the Toyota engine rebuild diagrams.
TOP: 21100- 18RG 18RGR 73-08 to 75-11 Wire choke connections single bolt holding jet cover on, ex 210 heads.
Bottom:
18RGU carbie 75-12 onwards Choke Rod and lever action multi screws holding jet cover on.

Good to see others with some enthusiasm for the good old Solex.
One correction to make about the sizing of the 40 and 44mm Solex/Mikuni.
The size is defined by the bore diameter at the throttle plate.
To convert a 40mm Solex to a 44mm Solex, one would have to bore the diameter out at that end of the unit to 44mm diameter and also source and fit 44 (#175) throttle plates and throttle shafts to suit.
Now if Sean is still working then he is indeed the man to contact about these Solexes.
I too have made good use of his services and knowledge over the years.

Hi,
Regarding the Type T version.
I have just successfully rebuilt one of mine with kits provided by Rodger.
I'd heard someone mention them not being repairable as well, but not sure why that would be. The friend helping me do mine had regularly worked with webber sidedrafts plus many other brands and didnt think anything was abnormal with these except for the extra diaphragm on the top being a bit of a waste of time if the rest of the pollution gear is missing.(Rodger also mentioned this to me as well)
I am thinking of taking photos of the pulled apart carby this weekend when I do the front one for reference sake on these Type T's
Dave
If you wanted to bore out the 40s to 44, use the ones with the older style bodies, as teh castings are pretty much identical.
Having said that, I haven't done it, and if I were to, I would bore out a rooted one first to make sure I didn't run into any holes.
Strong like horse, smort like tractor!

Couldn't be more correctOriginally Posted by Andrew162
All 18R-G (and in fact, all toyota "G" heads) were designed (and i think also made) by Yamaha. This includes the early 88210 and 88230 18R-G heads. Many people assume they are not Yamaha make/design because they lack the "Yamaha" in the front of the casting that the later models have.Originally Posted by RT104GT
I can assure you though, they are Yamaha.
...... butt scratcher?!
Agreed, I am just passing on scuttle and ill informed comments.
My only knowledge before these days was by word of mouth.

I've seen a few 3S-GE's and GTE's with a Yamaha sticker on the side of the top timing cover, but I've noticed that not all of them have it. It was just a black sticker with a white "YAMAHA" and Yamaha logo before it, so I guess they can easily fall off with age.Originally Posted by The Witzl
It is agreed that all Yamaha alloy headed Toyota use Mikuni Solex carbies?

Ok so MORE than a Yamaha sticker. I think the blank spot on the opposite side of the timing cover is where they used the 3S-GE / 3S-GTE designations with/out the Yamaha on the other side.
But I think we're digressing from the topic.
Mikuni PHH
Mikuni bought the Solex PHH license in the early 1970s and thoroughly redesigned it since then. The only parts in common between these two carbs is the diaphragm accelerator pump arrangement. The Mikuni now resembles a cross between a Weber DCOE and a Solex. They are the "set and forget" sidedrafts. Their flow rates aren't quite as high as the Webers, which is why they're not favored by racers, and jet availability is not as good. (Mikuni North America is the primary jet supplier). reference: bimmers.com
