engine missing

[Barrington Tennant <Tennant@tonline.de>]

Hi Alan!
I have only had one period of missfiring. That was after running for 2
hrs at low revs and power 4300rpm and 13 l/hr because I needen maximum
range to get to my destination.

I needed to push in full power to climb and for about 2 min. the engine
spluttered.

I think it was cold plugs in my case as the oil and water were at about
65 deg.

Best regards
Barry Tennant
