<p>Thanks Russ. I’ve neglected to reinstall the shim when I put the manifold and carb back on, probably explains why the idle is very up and down.</p>

<p>Quick question, should there be gasket cement (sealant) on both sides of the shim?</p>

Great to hear John. If your vacuum advance is original to the car I'd test it with a small cheap vacuum pump. It shouldn't leak down at all. My car ran fine but the vacuum advance was no longer working and was leaking. It ran even better with the fix.

<p>OK went back to timing - put in more advance from where it has just been set. That is the problem solved.. It seems to have more advance than recommended but I remember reading in another post that using more advance in these engines as they get older is necessary is that right?</p>
<p>Anyway car is running as it was before and no more blue smoke out the tail pipe!</p>
<p>Cheers</p>

<p>thanks all to start lots to think about. Tony the car is running Petronix 3. Before the head came off and on (left only) of course there were no issues -- car idled perfectly. I will get back on it today or when I get time and investigate further and update.</p>

<p>Did you put the metal shim back under the Carter carb? It will not idle with it removed. Was any sealant used between the metal shim and the base of the carb?</p>
<p>There is a choke idle adjustment screw, but not an idle adjustment screw. The idle is accomplished with the bleed air screw and fuel mixture screws.</p>
