i think the front right is ported vacuum. On mine i run the vac advance off the choke side vacuum port (full manifold vacuum) originaly intended for the aircleaner temp flapper. i don't really think this post qualifies as 2, so...

That's my $.01

Hey Rick

I'm still running the original set up on mine !

On the front of the carb,
- large barb is for PCV to left (driver)valve cover
- small barb goes to fuel canister

On the passenger side of the carb should be a tube, for ported vacuum, that runs to the distributor

The rear one, can be blocked with a pipe plug

Rick Thanks Rick.

How ya been? Trying to get some work done on this 70. Just so much going on.... Do you still have the vacuum choke on yours? I'm trying to decide where to connect the hot air choke to, or if I should change it over to an electric choke.

Andrew and I took the 72 down to MD show for the last hour or two of satr. I had to work satr morning and had to on sunday. We were only there for a couple of hours, but we got an honorable mention trophy out of it. you could have knocked me over with a feather when they let me know. graemlins/hurray.gif
