45cm rail, 3/8 Sugi Hara chain, 7 RIM, Ported at Stihlmar87

Comments: - - Great torq at the cuting! Sorry for asking but i buy a used 576 At with auto tune delete for zama 1c28. The seller told that saw with new piston seals and new bearings will be ok.

But a chainsaw deller say a two month journay and that saw will be dows for compression decrease from 160 to 130 in 20 hour work time. Have you heard that?

I clean the carbon deposit in cilinder and exaust exit and have no importand but litle scars from metal from the last bad bearings. In your opinion husqvarna Ls+ 1-32 racio is good and safe because 576 tend to stay lean ?

I would use a 20" bar with 8 teth rim (more 16% speed chain and lower 16% torq) but 450Nm/8100 can handle with that.

That 20 and 8 teth will killd the bearigs in 12" green eucalyptos? Thanks for your pro opinion.

Seems like you should be able to run an 8 pin on a saw that big with a bar that short not to mention it is ported.
