I was going to vote and then started to reply to posts and never got back to voting which I should
do as this has been a good discussion.
However the question is "which is best" instead of which I have installed or my criteria.
I only know CNW by website and a question as to kickback protection which I posted their answer to when the discussion started.
Do I like the CNW product because of fine machining and getting rid of primary case oil on my clutch? Oh Yes.
But kickback prevention is more important to me than oil on my clutch. And the CNW does not have kickback prevention while cranking according to their reply to me.
My thoughts are that the Alton works really well. The support for me was great when there was a
snag. My biggest concern is kickback protection should the battery voltage drop (which can happen
without one knowing).
It was mentioned that some members with an Alton have had their kickback dowels sheared in regular use (perhaps they have higher compression engines.) The Alton has room to put in 6 dowels but only recommends three to start. If the dowels shear in normal use, one can add additional dowels.
