Tom Lassiter Posted February 10 Report Share Posted February 10 I'm the new custodian of R4812, an R1 with an automatic transmission and an Edelbrock carb. When I compared my vacuum hose set-ups to the authenticity manual and other sources, it was clear that things were all wrong. I've managed to sort out some connections, but I'm unclear about others. The attached photos have labels with my questions. Thanks in advance for your assistance. Tom Greensboro, N.C. Link to comment Share on other sites More sharing options...
Fourward Posted February 11 Report Share Posted February 11 Number one is simply blocked off. Number 2 goes to the vacuum advance. I just put this carb in my car, works great. Link to comment Share on other sites More sharing options...

Fourward Posted February 11 Report Share Posted February 11 In the second photo, #3, the PCV hose, goes to the #4 port by the brake booster, and the port on the rear of the carb is plugged. You are correct in saying that #2 goes to the vacuum gauge. At least that is how my car is. Link to comment Share on other sites More sharing options...
regnalbob Posted February 11 Report Share Posted February 11 Number 4 is the vacuum line to the throttle kicker used on the original Carter AFB. Link to comment Share on other sites More sharing options...
