Hey all,

I have just completely botched up a carb rebuild on my glc (which is embarrasing because i am a mechanic, although i work on new injected cars).

I have been looking online for carb rebuild guides for these things and came across a gem of a pdf that completely outlines how to rebuild rx-7 carbs from 79-85. The index shows that there are installments for 626's and GLC's also but i can't find them anywhere. obviously whoever created the pdf had rx-7's in mind but clearly there is a document out there for the glc carburetors.

Has anyone seen such a document? or something similar? Much thanks in advance!

 

Please found below link, hope it's not too late as I just join this forum today.

Thanks for your efforts 5star, but that is the manual i have already located. It has some great stuff but it only outlines the rx-7s. the Contents page shows that the entire mazda range is covered, but however turned it into a pdf only included the rx-7 relevant info.

Thanks again for your help though

 

Totally agree, this manual was a very good information to understand the design of Carburetor. As I have difficulty to found mechanic have patience and knowledge to do maintenance on carburetor, I may need to do that myself.

Lurk, any suggestion and precaution on doing that? What need to be ready before? Order Carburetor Rebuild Kits first?

 

Definently buy the carbie kit first. Get to know the diagram before you start.
I would suggest removing the carb as a whole assembly first of all. Have a big clean space to work on and disassemble it slowly and methodically. DO NOT TURN IT UPSIDE DOWN! there are small ***** and springs in there that will fall out if you do. these need to be removed and new ones need to be fitted but i suggest doing this one by one with a magnet. This is the biggest putfall of carb rebuilds. Other than that just work through it step by step replacing everything you can one peice at a time.
Also make sure you buy a few cans of carbie cleaner and some very sharp razor blades. you will need to carefully remove all paper gaskets without damaging the metal housing. You should be able to set the bowl float following the instructions that will come with the kit.

All of that said, carbie rebuilds are reasonably advanced jobs so i would seriously consider getting somebody who knows a thing or two to help you. I stuffed my attempt up and i'm a qualified mechanic.

 

Control mixture of fuel and air inside this tiny little thing really a state of art! They have a lot of small spring and difference screw, really like a watch! This is the reason why I want to have an old car, learn something from base, reading books and search internet.

I will not disassemble it first, as now it has some problem can't return to idle. I don't think it's the spring problem, should be some dirt jam throttle axis. now it's rest at the service center. They claim that if spring can't found, need to replace the whole Carburetor, this is the way they repair old car.

 

That's pretty common. If you lose springs form older carbs its very hard to match new ones. i would suggest looking for a second hand carb at wreckers and using it for parts

 

Today I found a garage with a lot of half car and used parts, hope next week will have good news. The reason for me to buy a 91 Mazda was I like the tough body and nice engine, also support garage that have skill. As Car Manufacturing goes down and people lost their job, mechanic with skill but can't earn living.

 

Finally get back my car today, below was my bill:
- 2 Engine Mount
- New Clutch
- Gear Box Oil Seal
- Carburetor
- Replace B6 Engine
- Engine Oil and Filter
- Manifold Gasket
- Gear Oil

The engine now is quiet and stable, this was a big fix! $$$
