The early ZAs 1949 up until about mid 1951 (I believe I have the serial number break wrote in my parts book) were the ones as mentioned (back towards you is faster) the 1951-52 models were opposite (forward speeds up) one easy way to tell is if the 1/4" rod from the throttle is on the inside (to the right) of the steering support post then it is an early model-back is fast.
