Well I've got some run time milling with the 088 and the ported 390. The 390 will use more fuel than the 088. I milled some red oak I believe Saturday and got 4 slabs and made 6 cuts with the 088. It burnt right at a gallon of mix. Yesterday in some cherry I made 4 cuts and couldn't finish a cut twice without a refuel stop with the 390. The oak was 7' or so and the cherry was 9'. The cherry was narrower until the last cut. I didn't measure then exact but may to keep track of fuel usage for bd ft milled.

Would you consider the 390 a viable option to run a CSM? Been kicking around the idea of getting CSM but figured I would need to step up to at least a 394/5.
 
I wouldn't want to run a 36" bar on it like that all the time. Maybe a 32" bar and some smaller wood than I was in. If fuel usage doesn't matter then by all means tune down some rpms and go for it. An aux oiler wouldn't be a bad idea either.

Fuel usage really doesnt matter to me. I am considering milling to get some bigger slabs (40ish") so it looks like a bigger saw is in order but nice to know the 390 would be up to it in a pinch. Thanks for the input.
 
No problem. I know now to make sure to have more than 2 gallons with me if I'm milling with the 390 for more than 6 cuts.
