timing question

[shawn sto]

does anyone know what the timing on a 1979 inline 6, 2 barrel weber carb with a comp cam, should be??

Initial advance should be 4-8 deg advanced.... with a target of 6. Go too far and will not start well and could rattle too...

Here is a very good write up on the WEBER/Jeep Combo. Read the links and will show you lots of tricks to make you Weber and ignition run better.

here is the weber/jeep tune link

Having a non stock cam will also affect your set up and time curve...

once you change cams your kinda on your own with timing depending on how big a cam you go with. Chances are you will end up with more than stock though. Just be sure you don't get any pinging under load.
