VM,
Idle ill be a LOT smoother with more idle timing, probably wth 35-40*. You can simulate this by using an adj vac adv unit hooked to manifold vacuum [ MVA]. 5 min to test the benefit: simply turn the dist [ advancing ] with engine idling, in gear if auto. Advance until rpm stops increasing, THEN check the timing. RPM increases because engine is making more hp. Result is cooler running, better tip in response, smoother idle, more vacuum. I could give plenty of examples, here are just three:

Legend Bewy, thanks heaps mate. Idle is pretty good with 22-24, no rpm drop when pulling it into gear. I have adjustable vac advance on the dizzy, so I’ll give MVA a go, got it on ported vac right now, also tried no vac advance.
I have the vac canister set for 6 degrees only ATM. (crank degrees).

Should get more control of idle mixture screws if all goes well with MVA instead of ported. - cheers for that info!
I’ve got some info from Rhodes about the lifters. Have to check my notes, I think the ppl I bought them off may have given me the wrong install instructions….. I’m seeing a glimmer of light now. :)
