I also have the HM130, bought it several years ago. It is not mobile, as I wanted to be able to cut 20' logs (much harder to find them straight in that length). Last year, I spent more time trying to keep the engine running than I did sawing, and finally decided that since it is not mobile, an electric motor was the right solution. $1000 or so later and quite a few hours puzzling over electric motor starters (that I was completely unfamiliar with), and it is up and running. Did my first cuts on a 20' x about 25" log yesterday. It went well, although there are design flaws in the machine so that it is not possible to center the log initially. I've got a plan to fix that. I will agree that Woodlands' customer service is awesome, but understandably were not really up on things when it came to the conversion. Now I've just got to figure out where the clog is in the lubrication system...
