He gets a lot of big logs from a local tree service guy, the 362 was really undersize for many of those. He's running an OWB year round for domestic hot water in 2 homes, a hot tub, and a heated pool (he said the pool was 90° F this week, night time lows have been in the 40's for about 3 weeks) so they go though a lot of wood. For summertime operations soft maple, cotton wood, etc. are used and many of those grow pretty large around here.
Thanks Steve, Chris also offered one...for now we decided to use the Duke's kit and leave the crankcase as is.
