Rotax 80hp, ignition problems

[Wheels]

don't forget that the image you are seeing in the video is a product of a video shutter speed that exaggerates the movement. Still, it highlights the excessive movement of the carbs. I could send you the one I took of my own engine but they look identical.
Watch AVwebs video tachometer film. its a trick I learned from Brian and Carol Carpenter but its spot on. It illustrates the shutter speed deformation of imagery from a rapid oscillation or a propeller movement.

Thanks for your inputs.

The carburetors sockets are new, the spring is there and meets the 40 mm length as per manual. I inspected the engine mount again for cracks today and couldn't find anything obvious ... I am planning to use this special coloured spray which penetrantes in the cracks (don't know the technical name)...

What should be the torque in the attachemnt bolts of the engine mount to the frame?
