Narrative:

During engine start the right engine appeared to start normally and stabilize. The maximum start red egt line disappeared and there were no EICAS messages. As we were starting the left engine; no. 2 spooled up slower than it should have and max motoring was approximately 10%. The pneumatic duct pressure was also low. We quickly checked EICAS again and looked for the source of our low pneumatic duct pressure. Then the captain noticed that the right engine start selector was still in ground. He set the selector to automatic and the left engine immediately began to spool up normally. We continued the start on the left engine. Before the left engine stabilized; the mechanic stated that our right engine was on fire. The captain immediately shut down the right engine. From the tone of the mechanics voice; and since we had just dealt with the starter malfunction; I felt there probably was a fire in the accessory portion of the engine compartment. The mechanic then stated that there were still flames coming out of the right engine. I immediately requested that the tower (via ground control) send the fire department to our aircraft in case the fire continued to burn. The captain discharged the fire extinguisher bottle by rotating the engine fire switch. I believe this was the conservative action in this case. The mechanic stated that it appeared the flames were out. The fire department arrived at the aircraft approximately 4-5 minutes from notification and confirmed that the fire was out.

Title: After the B757-200 flight crew shut down the right engine to the failure of the pneumatic starter to disengage; the tug driver advised it appeared to be on fire. When the fire persisted the flight crew discharged the fire extinguisher bottle and called for CFR assistance.
