Ed,

Thanks for the follow-up comment. I have been able to find several people with this issue over the years (posts going back 8+ years), but solutions have been much harder to find. I'm glad you provided your solutions that have worked.

The breather is one that I was going to look at next if this didn't fix it. I did run compressed air through the breather and lots of 'stuff' came out, so this could have been part of the issue also.

So far, so good! Thanks for your reply - I'm crossing my fingers that the issue is not 'heat' related - and repeats itself as the weather warms up. -Doug
