Carburettor service kits.
Fantastic thread and great work Mac, just wanted to say that a scanned version of my green books....(sadly the originals are now lost) is available through the technical section of this forum and gives good info, although its a shame the pictures didn't transfer a bit better, in the original books they were very clear.
Right, my first question. I knew it wouldn't take long. I took the oppertunity to take the carb off today as i have permision to leave the car where i work untill the after the weekend. In doing so and using the photos i posted earlier, the baseplate gaskets look to have the two guide off set guide holes in deferen't places (Nearer the middle) Does this mean there are differen't generations of this carb, and the kit i have is not compatible. I'm not keen on stripping the carb down unless i know it fits.
Cheers

Hi Carl,
You should find that there are two insulating blocks fitted on your car - a thick black block (with the breather pipe connection) and this should use the two black gaskets in the photo of your kit. Between this block and the manifold is a thinner insulating block which has the two pins and should use the "beige" gaskets in the kit.
But yes there are several versions including one with a green insulating block and a rubber coated steel shim.
My "how to" guide is now finished and if you can PM me your name/address I'll gat a copy off in the post to you (14 pages fully illustrated).

I just want to make a public thank you to Mac, I've already thanked him via a PM conversation we've been having over the last few days. Anyway Mac sent me at the end of last week a guide for doing the service of the solex 28/34 Z10 Carb.
I've been having problems with the car for a while and even tho i managed the engine change i wanted to rebuild the carb as i thought that was the root of a few of the problems i was having, but was a little wary of getting right or losing damaging bits.
I took my time and covered my kitchen table with white paper to circle and note each part that came off, cleaned and rebuilt with the service parts via Mac's guide. The carb base was also warped and i was worried it had gone to far, but i took my time and sanded it back flat.
I've put the carb back on the car now and have to say it drive so much better. Gone is the horrible dead spot when you press the accelerator and it idles a lot better.
I need to get it adjusted correctly, but I'm hoping this will all go well and some of the previous problems are corrected.
Anyway as i said at the start.
Thank you Mac, Great Job

Enjoy your 300s
I've just managed to talk nicely to a local MOT center and got the chap to do an emmissions test on the car in between tests and the results were 0.24 for CO2 and for the HC it was 84ppm, which are well below the limits. To be honsest he was quite stunned on how low they were.
So Iguess this means that it's probably running a bit lean and there is a bit more power to be got from it?
It's running well at the mo, but does feel a little less powerful on acceleration.

Yeah you need to be at about 1.0% CO, its running a little lean, you should be able to adjust that out by backing out the idle mixture screw in the base plate.
The easy way to adjust the carb mixture which will get you roughly within limits without going too lean is as follows:
Get the car nicely warmed up, ie: drive it for at least 15-20 minutes,
Unscrew the idle mixture until the car idles at its best, ie: smoothest. Readjust the idle speed to 950RPM. That'll get you to about 5-6% CO, too rich. Then you do as follows. Screw in the mixture very slowly until the idle speed just dips again about 50rpm. That'll get you to about 1.5-2.0%, plenty within the MOT and the manufacturers specs.
