Last season I replaced the door gasket. I tried the dollar bill test, tight , but i could still pull it out. I would like the door to seal up and close tight like my new 3CB. Anyone know the biggest size gasket I can replace it with to tighten up the door? Any suggestions on the ash pan gasket too? My window gasket sealed up nice and tight and luckily I didn't crack the glass. Could my door hinges be wearing out?
