Yesterday decided to carry on with work on the van, I first set the throttle cable as that had never been set properly following removing the pump numerous times, then I moved down to the kick down cable which was miles out. However the kick down cable is goosed, the flexible outer has pulled out of the clamp/adjuster tube so I ended up backing it right off as it was jamming - just need to find a replacement now. †Moved onto the TPS, that was 1.2v and I got it down to 0.78v which was at full adjustment. †Seems to run better with no kickdown but I haven't really been out in it; I'll get the replacement cable on and see.

So now it's on to idle speeds, when cold the tick over is about 400rpm and hot about 600; cold it ticks over okay but sounds like a bag of nails, if I increase it to about 600 using the accelerator it sounds much better though still noisy, the rattle doesn't go away until it warms up now.

What idle speed should I be aiming for and how/where do I adjust the cold idle speed?

Cheers, Andy

Normal, factory set, idle speed is 800rpm.

As Lewis sez, 800 RPM.

I suggest that be the minimum for an old engine (mine idles at just under 1000 RPM)

Too low idle RPM's  may not pump enough oil at a suitable pressure to prevent wear.
Plus the vibration, as you've found.

Thanks for that, makes sense Deker, but where did you adjust the cold idle?

To set cold start tick over see diagram, itís a pig to get too.

Mine †is set at 800-850 rpm in park, notice revs go up in park and neutral, and drop when in gear.

To achieve my chosen cold RPM the gap on the threaded adjuster is 10mm.

The top adjuster is to advance or retard the pump timing when cold / see my other post.

And the obvious adjuster not shown in picture is the general tickover screw which comes into play once the cold start mech governing arm is disengaged.

Lewis the throttle cable adjusting nuts makes no difference to the cold start idle as the cold start idle is independent to any cable, in fact it doesnít have a cable it is spring loaded.

Can you fix my link when you are not busy, thanks .

Missed the 'Cold' bit, so removed my unusable advice.  Very Happy

Your image link will not fix as it is in a strange sort of format, which will not convert to a url link, back to Photobucket, unless you have an account with them.  Sad

As the image is 1440 pixels wide it is also way over the maximum permitted 800 pixel limit for images, though 640 pixel is much better for uploading and downloading speed, especially for those using smart phones.

When I try to remove the URL's the whole post goes blank.  Confused

Seems like facebook is still trying to stop 3rd party usage.  Shocked

Simplest option is to post smaller images, as previously mentioned elsewhere.  Smile

But on a positive note 😂 I did it anyway!

It was a bit of brain work though as my cold idle screw has a slotted end not a hex, but luckily my A/C compressor is goosed and the system empty, so I took the pipe blocking access off the compressor and then could get to it easily. I still couldn't work out what would happen if I managed to turn the screw as everything seemed fixed together, so I slackened the nut on the end of the cold start shaft and then everything moved independently and became easy to follow. I managed to take the pressure of the adjusting screw and it turned with my fingers.

Should I have had to slacken the nut though?

Anyway, cold and hot it now idles at 800rpm,

Cheers, Andy

You will be familiar with this then, glad you are sorted.





Very Happy

Yes that's the baby, still sounds a bit rattly but not as bad and idles well now.
