Narrative:

On takeoff with the captain flying; the aircraft lurched to the right just as the takeoff roll started. The captain stated that the engines did not spool evenly and he then reduced power on the left engine and used (I think) left tiller which then caused the airplane to lurch in the opposite direction. At this point he got the aircraft under control and we continued the takeoff. Everything seemed normal from that point on. After takeoff another aircraft on the ground noted that our nosewheel appeared cocked on the start of our takeoff roll and stated that he saw it smoking for the first 1500 ft of our roll. We continued and landed safely. The captain called maintenance and there was no damage. Don't rush. Take more time aligning aircraft before applying so much power or abort if unsure.

Title: B737 FO REPORTS DIRECTIONAL CONTROL PROBLEMS DURING CAPT'S TKOF DUE TO RIGHT ENGINE NOT SPOOLED UP.

Narrative: ON TKOF WITH THE CAPT FLYING; THE ACFT LURCHED TO THE R JUST AS THE TKOF ROLL STARTED. THE CAPT STATED THAT THE ENGS DID NOT SPOOL EVENLY AND HE THEN REDUCED PWR ON THE L ENG AND USED (I THINK) L TILLER WHICH THEN CAUSED THE AIRPLANE TO LURCH IN THE OPPOSITE DIRECTION. AT THIS POINT HE GOT THE ACFT UNDER CTL AND WE CONTINUED THE TKOF. EVERYTHING SEEMED NORMAL FROM THAT POINT ON. AFTER TKOF ANOTHER ACFT ON THE GND NOTED THAT OUR NOSEWHEEL APPEARED COCKED ON THE START OF OUR TKOF ROLL AND STATED THAT HE SAW IT SMOKING FOR THE FIRST 1500 FT OF OUR ROLL. WE CONTINUED AND LANDED SAFELY. THE CAPT CALLED MAINT AND THERE WAS NO DAMAGE. DON'T RUSH. TAKE MORE TIME ALIGNING ACFT BEFORE APPLYING SO MUCH PWR OR ABORT IF UNSURE.
