Vacuum hoses on the 1200 follow a simple layout.
Overview
1. VACUUM ADVANCE
Vacuum Advance
Connect a hose from the distributor to the port connection directly above the idle mixture screw.
Vacuum advance in all models uses a hose from the 'port' on the carburetor to the Distributor.
The A12 will run good with the vacuum advance disconnected, but will run smoother and get better fuel economy with it working.
