Rough running and smells very rich
#1
After an epic fight with the clutch slave cylinder removal (involving a fractured rib in the process), I now miss driving my car.  As it's only the clutch not working I started her up.

This started the extra smell I never had before, a lot of extra smoke,  lumpy running and smelling very rich.  The engine moves about a lot too.

Where should I start looking for a resolution.

Also, tips on clutch slave cylinder replacement...........

Rough running could be a few things...

Not run for a while.
Old fuel.
Upset mixture


Changing the clutch slave cylinder involves assuming the superman position. I used step ladders to support my legs while I hung my head and arms down the back of the engine. You need to jack up the back end or use ramps too, as you need to undo the slave from above AND below the car. (Or at least I found it easier to do like that)

If you don't want to assume the superman position, then access can only really be made by stripping down to the VOD. This allows you to see the cylinder in a more conventional manner, but it also requires a hell of a lot more preparation and parts for reassembly.

I did mine last year. The superman worked for me. I pulled the old one out in about 1.5-2hrs of struggling, and then took about 1.5hrs to get the new one into place the next day. (Reassembly is quicker than disassembly, due to corroded parts and struggling to get undone + unfamiliarity. Gained familiarity allowed me to get the new one in fairly pain free)

I hope this helps. Good luck.

Access to that area is much easier when you have the S/S exhaust systems and no cross-over pipe. (and a lift to work under!)

Good luck with getting it sorted. Just remember that things don't 'go out of adjustment' by standing. Something may have stopped working. I'm into fuel stabilisers these days but it, usually takes a few years to go off in the UK.

Might be worth checking you have not unwittingly knocked off any of the vacuum pipe connections. While assuming the "superman".

Also did you have the bung covering up the mixture adjustment screw? That would also be in the line of
fire so to speak in the area above the clutch slave that you would be leaning on top of.

Is there a vacuum pipe layout diagram I could use to make sense of the many pipes back there.  Also is there a picture of where the mixture screw?

I think it's fixed. The centre line into the charcoal filter was completely off!!!!!! Many thanks for the help.

Great stuff, glad you got it sorted. Like Chris mentioned above, I find removing things the easiest way to do the slave. Even if it's just the fuel distributor/air intake part, it really does help.
