190E 2.3 8V Iginition Timing

[professor]

I don't know if what I did is correct or complete.
I moved the front balancer until the T mark was right on the pin that sticks out on the block. I then moved the ignition distributor and lined it up with the notch on its housing. When I turned the car on the T was spot on where I set it as I used a strobe light to look at it while set at ZERO degrees.
Was there anything else I needed to do? The car does backfire if I push on the throttle while in neutral. By the way, this a 1988.
