Sounds about like mine, between some age and miles (180K mine) and overly heavy 15w40 and weather in the 30-40 range here I'm not surprised. It was pretty quiet over the summer, and it quiets up pretty quick once in motion. I might put some lighter oil in it for the winter, I know these motors like heavy oil but it seems excessive. I'm open to suggestions too speaking of which, something I can buy local.
