Post subject:  Rough idle when warm...suggestions?

I have a '65 Barracuda /6, with a rebuilt carb (1bbl Holley model 1920) and a Pertronix ignition. Car starts and runs fine when cold but once it warms up, the idle in drive with brake on is rough and it sometimes stalls. If I pop it into neutral while sitting at the light, everything's fine.

Timing is right on and I've bumped the idle up to about 900. Don't want to go too high. What are some other things to check?

Thanks!

Adjust the valve lash carefully and that will likely fix it.

Best,
