6900 and 6901. Just for fun a couple you tube videos.
The 6900 is quite mild and the 6901 is a bit angry at idle. Interesting the @.050 specs are a bit different but the advertised specs and lift are similar. Listen to the videos. Of course the timing and carb adjustments are different.
#6900 1200-5000 rpm
