[DMCForum] Re: My first tune up

["Mike Bosworth" <mike.bosworth@xxxxxxxxxxxxxx>]

Hi

There always seems to be much fiddling done with this damm screw ....

Its a simple task to hook up a dwell meter and set this to the 
factory setting, all as shown in the manual ..... and hence with 
none of this guess work that goes on... or maybe there is suposed to 
be an air of mystery going on here :)

Kind Regards
