Spark Plug Changing

[amjad]

Hi Guys,

This request may seem quite trivial to many of you and quite funny to the rest!

Question: How do you change th espark plugs on C180?

I have taken off the metal cover under which the plugs are by removing the three Allan key nuts. After this I was not able to 'pull' out the red/brown plastic which houses the plugs. What am I not doing which I am suppose to?

Any help will be much appreciated.

Thanks

Regards
