How many degrees timing advance MS 400?

Spooky. Your backwards. The saw rotates counter clockwise when viewed from the flywheelside. You want to make the fly wheel go further or "advanced" in its position counter clockwise relative to the crankshaft so the spark happens sooner.

Magnet gets to the coil earlier

Do u remember a 67 cc saw with actual torque? Ignition are so aggressive on the 680/620/7310, u dont have to mess with em.

Still in production and will over oil a 32" bar.

Most echos have aggressive timing like that which is part of what adds to their torque.

i like 10deg

I thought maybe the magnesium piston of the 400 couldn't handle the extra heat as well as the 362, and since they share the same flywheel, the 400 doesn't seem to be cooled any better than the 362.

But just to be sure, does anyone else notice the saw getting hotter with an ignition advance, or at least not experience any problems with it, not even in the long run, not even with a 10-degree advance? If that's the case, that reassures me, and I'll keep it that way. Thanks for the replies anyway.

It's strange, by the way, that they advertise the 400.1 as having improved cooling. If that wasn't a problem with the old 400, why does the 400.1 need better cooling?
