I don't know where you could get one. They told me it was for cold climate operation and not needed here in Oregon where I live, don't know about Maine. Your carb might be the problem, they are a lot of the problems with the 2.8. They are a lean burn carb (electronic control 2 stage 2 barrel). Make sure the choke is set right. Just throwing out ideas, hope some of it helps. I drove one of these for about 15 years and might have a decent carb laying around.
