Narrative:

Maintenance performed a check of the left thrust reverser before our departure based on the inbound crew write-up of a noise in the left reverser. They determined it was working correctly and serviced the left hydraulic system which was slightly low. We started the left engine during the pushback from gate xx. There was no delay in our single engine taxi out of spot Y. Once we reached taxiway K we started to smell something like a burning smell. When we began our left turn onto taxiway left the cockpit began to fill with smoke and fumes. I instructed the first officer to call the ramp back and tell them we were returning to gate xx. I told ground control the same and called the flight attendants to assess the cabin situation. They had the same conditions but were in agreement we could return to the gate under the present circumstances. Our total time from out to in was 9 mins. I did not declare an emergency since our return to the gate was unobstructed and quick and the situation in the cabin seemed under control. When I arrived at the gate; the smoke and fumes had dissipated and my plan was to leave the passenger on; however the smoke and fumes started to fill the cabin again and I instructed everyone to exit via the forward entry door in a timely manner. Supplemental information from acn 707450: after push out we started the left engine and began to taxi. As soon as I turned the packs on after engine start we could smell smoke. A few seconds after that we could see smoke in the cockpit and opened our windows. Then the flight attendants called and said they had smoke in the cabin. We turned off the AC packs and decided to go back to the gate.
