I think youll find that Skydrive source replacements direct from Bing and they
are less eye watering in price.
I changed mine after they had done, according to the records more than fiver
years
and it may have been longer. They had no cracks even though Ive prodded and
poked them very well but changed them anyway as I have with a number of items
since buying the aircraft to get a known vintage on life parts.
In MHO if you have the air box fitted and it is well supported then the carbs
dont
move on the mounts as much as those who use the cone filters and relying on
the springs Rotax put on the carb, hence putting less strain on the rubber
flanges.
