RD, on my car I have a "Y" connection coming off the top of distributor actuator. One line goes deep into the front of intake manifold. Other one goes off to another "Y" connection that goes to a dual port temp sensor?? on front of intake manifold. I'll see if I can get some pics tomorrow.Anyway, moved that one line and did seem to make a difference, more responsive to throttle. This has been a long process.I've been doing this without proper instruments for measuring combustion,fuel pressure, etc..Initially I had this weird humming sound. That took most of last summer to find. Turned out that the fuel pressure was too high,I started removing shims from primary fuel regulator until it stopped. Then I've been dealing with a hard start when hot situation.I've been backing off little by little on the fuel mixture screw(inside FD ). This has gotten much better. I feel that I'm almost there. But, still have a throbbing at idle. Thanks for all your help...
