Unfortunately there will always be those that think they know better than the engine manufacturer. Hopefully this won't end in tears at some point in the future with posts on problems with the engine.
Mind you, I can't help wondering if this is a bit of trolling & the OP hasn't actually got an engine. Things like the bag incident just seem a bit too contrived.
Another forum has the 'custard test' where a picture of the item is posted with a tin of custard (preferably Birds
) on it to show that the poster actually does have what they claim. I look forward to being proved wrong.
