I recently got the above machine and one thing that I am not sure about is the fit of the seat around the engine hood. I have seen lots of pictures on the net and the seats all seem to hug the engine hood. Mine seems like it has spread open leaving unsightly gaps. Is there a way to heat up the plastic to squeeze it back inward around the engine hood? My fear is the plastic is of a type that does not behave with type of treatment and will just settle back to it's current state. Does anyone have any ideas on what works or what I can do?
