Im not 100% positive, but it should be a normal firing order of front and rear firing opposite of each other.

It's a valid question.  Posted in another forum:
>>
Starting at #1 TDC (firing stroke) the engine then rotates 288 degrees (360-72) and #2 reaches TDC(firing stroke). Rotation continues past #1 TDC (overlap between exhaust and intake phase), continues 360 degrees and reaches #1 TDC (firing stroke again) completing the firing sequence for both cylinders (360+72). I've done the valve adjustment on a couple of these, so I know this to be so.
