How do you replace the ignition module on a Tec HSK70?

So I got a new ignition module as mine seems to be unhappy when it's been working for a while.

How do I go about getting to it? Do I have to remove all the shrouds for the engine? Do I need to remove the chute rod as well (Ariens ST724)

It's under the flywheel housing, on top. Have some sandpaper to clean the magnets on the flywheel. The spacing between should be the thickness of a business card.

Yes and 3 of the head bolts, then the throttle control, 2 small bolts on the bottom sides. Then it pulls out. Some snowblowers you may need to remove some stuff on the handle. While it's out, check the condition of the pullcord. The spacing is the most important as it controls the ignition timing.

I actually just replaced the pullcord last week. was hoping to do the ignition, but will wait until the spring or an unseasonably warm day to start that.
