I wouldn't have thought fuel would be the major corporate here at 4 galons it just seems too early, I was going to make the switch to byrons 30-9 but now I don't think I will reading the responses here about this issue even though I think it's more than just a fuel issue at 4 gallons there must be something else that's gone on and if the OP has a speed with 8 or 9 gallons on it could just be a faulty bearing or dirt/grime. Maybe you could share some pics of the bearing if available so we can see what it looks like. Novarossi are kind of reminding me of Apple and their iproducts with their bearings not being available anywhere else out there but from them .Can anyone manufacture this bearing if they chose too? They would probably alter something else when that happens anyway, I mean you can look at it like smart business or poor business I suppose depending on your view of it, me personally I don't like it and think they would sell more units if replacement bearings were readily available atleast at the current cost of them anyway it's rediculous like Op is saying he is already contemplating just swapping the mill out for something else at this point already. Man I'd be bummed wether it was poor maintenance on my part or not I still wouldn't be happy.
