Subject: Re: Suitable Spark Plugs for 16/80?
Just to add to this thread, it's probably worth pulling the engine out during the winter and checking it over. New rings would be useful but above all get new steel rods and shell bearings if these have not yet been fitted. I'm sure BG will do this for you if you do not have the facilities to do it yourself.
In the mean time, let the engine rev nicely to burn off any oil and note H81's advice regarding getting the carbs right. Above all, have fun getting the engine good and hot on a decent run.
