Hi,

I am looking information about the chainsaw ignitions that have automatic advance. The manufacturers websites give little in the way of details, ie;

How many degrees of advance are provided?

At what RPM the total advance is attained?

Is the curve linear?

How heavy is the system, less flywheel? I'm comparing it to a CDI with a battery capable of storing enough energy to operate the system for up to 4 hours.

Is the whole thing built into one unit or are there seperate parts?

I would very much appreciate someone directing me to where I can find out the answers to these questions. My local chainsaw repair shops haven't encountered a reason to work on or replace these units and so have no experience with them. From what I can tell, all the brands are covered with lifetime warrentees.

Thanks very much,
Dan Clarke
