I checked compression a couple years back, 100 and even. She has good power when running. I guess I could check again. Carb cleaned. It has had this hard start for the last 5 years or so. It sat for the last two years but I'm getting her going again for some work this summer. Back 10 years ago she started much easier....But I can't point to one thing I did to cause the change. But I have made a lot of changes. 12 volt conversion.
