Found the price of $180 to be a bit more than expected. I am certain mine is bad. After it sits overnight, it seems harder to start. When warm, it fires right up. So something seems to be leaking down when it sits. Given the age of the part, I would rather replace/fix it anyway.

I am guessing its not a part that can be rebuilt, but I thought I would check before spending $200 on a part.
