my 1009 after an initial start and drive to work (15 min warm up 15 min drive) when i shut it off, if i go to start it again an hour later it just turns over ,if iI wait longer say 2 hrs it will start right up. I carry a can of wd40 with me but it is kind of a pain to spray and start at the same time.new filters have been installed no change. any help would be great Thanks Thom.
