"Old" Plug Gap

in 912 / 914 Technical Questions 5 years ago

What is the correct gap for the NGK DCPR 7E plug used on the 912 UL before Rotax changed the plug in 2020 ?

It seems that the Jan. 2020 Maintenance Manual update gives the gap for the newer Bosch plug.

Thanks for the help.

    Hey Bill,

     

    Is there somewhere we can download old maintenance manuals? I am specifically interested in an older one for the 914.

    I do not download 914 manuals as a rule as I am a 912is guy.
    Roger or the ADMIN may have some in their archives.

    What year are you interested  in?

    My engine is fairly new (less than 3 yrs) but I am interested in things like the old plugs, fuel specs, etc. and generally comparing to see what has and hasn't changed. Not terribly important, more of a desire for additional reference.
