The Mikuni gasket kits (US) don't have in them the pump diaphram, did you get those separately? https://www.jauce.com/auction/1155785394 This what they look like if you don't know. From my experience the gasket kits from Japan do/more likely do come with the pump diaphram than the US kits.

The texture is what's left after the serious corrosion on the trumpets was removed, not from my work. I could have changed the trumpets out, but the other carb has a cut-away on the trumpet particular to a car model, so not something I wanted to try to replicate, therfore let someone else change. I strip the carb, thread holes cleaned with the correct size tap, everything goes in an ultra sonic bath (with plenty of soak time without ultra sonic [I have some laboratory neutral detergent]), cleaned, dried. Blasted (wet) as its easier on the surface (not with anything really abrasive), cleaned, dried, checked. Steel parts get the same treatement before yellow zinc. New genuine gasket kits and replacment parts, esp idle mixture screws replaced wether needing or not (as a groove can get worn creating inconsistent idle). Its quite a bit of work, takes time.

Nice Nils! These are type 4 PHH 44's, there are different types, and gaskets differ a little. I restore and rebuild these in my spare time, so by the time you replace all the gaskets, its essentially a strip, clean and rebuild. The pump diaphram at the bottom of the carb is where most of the crud sits, and the diaphram is worth changing. I find them a nice project to do. Here is my before and after;

Nissan did make wiper blades for high speed, I have a pair NOS for the 510, with a blade to help with downforce. Though unsure if there were Nissan ones for the the S30, without checking. Yes, a common problem with the wiper mechanism, slow and not setting back, most swap to the Honda(?) wiper motor, but a through clean and re-grease may do the trick.

Oh some of those photos didn't work well...

Spotted this Sports Option diff cooler and pump. Thought it would be interesting for some. @HS30-H can you say anymore, pump under rear floor mounted, bolt holes already exist? The auction listed it for the Fairlady Z.

Hi Kats, Unfortunately the shipment of the spray cans was cancelled shortly after placing, even shipping by sea from Japan looks not possible.....

Sucessfully ordered from Japan! Shipped by sea. More than 1, as min number could be ordered from supplier....

That's what I have just done, I don't need now, but as its cheaper now, and I had no shipping cost (in with parts bulkier/heavier).

Spotted this on my Yahoo trawl.... https://www.jauce.com/auction/w1150380520

Jeff, I pointed out these retaining rings in post 40, here is a link; https://www.jauce.com/auction/w1147945499 Unless H30-H or Kats know of another place the get original or someone else who makes these, velo1955z is the only place I have found. I have another set of rings arriving today from Japan.

True, but sites like Jauce let you buy NOS parts and other rare parts, if you want, like I do, its the price that needs paid, otherwise there wouldn't be any restoration.

And here are some reproduction bleed nipples; https://www.jauce.com/auction/w1137033573 The auction has finished, but the seller has listed and sold 2 or 3 sets now, so hopefully more would be listed later if you require Jeff.

The pistons and seals are available; https://www.jauce.com/auction/r1144731421 And can be brought separately. Pistons, in theory, should be available from Nissan. What is also needed, which isn't in the seal kit, are the seal retaining rings...which are avail repro. Stainless instead of steel. Helps keep the water out of the piston. Here is a listing with the maker of the seal rings; https://www.jauce.com/auction/1115276814

The Project Mµ correct pads are about $57 , plus bidding fees and shipping, no doubt under that price of $230 +. Project Mµ great stuff, suitable for street and race, I think from 0-400 degrees C. https://www.jauce.com/auction/w1138774065
