I have started my WCPCL in the barrel with Bosch M10 AC spark plug.
Fit nice into the engine and start good.
I hope that I will test it on the sea this summer.

Happy Seagulling!

Igor,

Baybe someone could supply a cross reference chart e.g
Champion-Bosch. This may help you to find the correct spark plug
as most know the Champion type.
I have tried Bosch M 5 A on a 102 but have only limited experience, works fine in the garden...

regards
Sten

Hello Igor,

On the net I found (in comprison with Champion D-16) the corresponding Autolite which is e.g. B9 and corresponding AC tis 86.
Could the international Segullers fill in this format which could a cross referencew chart for Spark Plugs suited.

kind regards Sten

The plugs today recommended and sold for Seagulls by British Seagull are the Champion D16 and the D21. (Think the D21 might be a hotter plug for use at low revs...) I have never used one and often use low revs with the D16 with no ill effect.

The equivilant NGK plug I often used to sell was the A6. Both these plugs are now classed as 'speciality' plugs with a price match!

Of course the old plug was the '8 COM' but these have been discontinued for many years, as has the even older Lodge plug???

I will look and try and find a full list and add it to the site.

You can get cross reference from one brand to another at

(WHere else??)

www.carsparkplugs.com

I did try D16 and it didnt list a Bosch equivalent though....

However, it does confirm the NGK A6 as the 'equivalent' to the Champion D16, and Bosch site confirms CHampion A16 can be replaced by:

M7A

M8A

M8AC

M8ACO

M8AO

M10A

M10AC

M10ACO

M10AO

M45T1

M95T1

M95T5

M145T1

M145T5

M175T1
