I have the same issue. So following this thread with interest. Is there a guide on how to remove the swirl flaps.
Not needed with diesels.
I re-use them, unless there's obvious damage.
This would also fit in to the new petrol engines being designed. there is no vacuum and runs like a diesel, and the flaps can control the mixture taking it down to the leanest burn possible something like 14 to 1 if I remember,,and getting 4 to 5 sparks per stroke. The same engine had no running gear,,all of the valves were controlled by solenoids
