Narrative:

I elected to start 2 engines at the gate using an air cart. Communication with ground personnel was extremely poor on the headset; so alternate hand signals were used. After being on the MD80 for 19 yrs; a 2 engine start at the gate was a normal occurrence. I have been on the B737 for only 2.5 yrs and did not remember that a 2 engine start at the gate with an air cart puts maintenance/ground personnel in harm's way when the air ducting needs to be disconnected. I received clearance; via hand signals; to start the second engine after the area was safety checked. During the engine start; my copilot observed that the line mechanic was not happy with the developing situation; so I terminated the start process. No injury or damage resulted. The aircraft was pushed out of the gate and a normal engine xbleed start was accomplished. Contract personnel did seem puzzled that I was starting the second engine at the gate.
