J4RSSM power pack/ignition module air gap

[AdrianTurner]

Been searching the internet and this online manual Boatinfo - 1990-2001 Evinrude Service manual trying to find the correct air gap for my Johnson 4hp (2000) power pack/ignition module but can't find it anywhere.

Do any of you guys have the answer?

If you look at that "book" around section 4-30 it refers to either marking the unit before removal or using a makers location tool to refit correctly. Have you taken yours off?

[AdrianTurner]

Thankfully I haven’t taken it off or even disturbed it but due to it not running smoothly and finding a couple of previous 'Cowboy' fixes, I thought I would get all the needed data together before going further. That manual seems to have all the air gap tolerances except for the model I have.

The section stating

either marking the unit before removal or using a makers location tool to refit correctly

refers to the 2 & 3.5hp engines

After re-reading page 4-45, and even though it does not actually state it, I have come to the conclusion that on this model it is not adjustable, which seems a little bonkers.
