I bought a saw from him
Bought a rebuilt 066 from him. I think everything was new except for the case. Even gave me a warranty which I never used. Great saw and he gave lots of extra items even after I PAID FOR IT and it was shipped.
One of the better items I purchased and the best I have been treated after the deal was complete.
I am guessing he is a firefighter or works in the forest service since the boxes he shipped the items (I bought) had US Forest service crossed out on it. I think he works with SAW-KING in building saws.
Most modifications he is talking about on this auction can be done by most any experienced engne builder. Ask him ... I think he will tell you what he knows about the saw.
In my specific case he stands behind his product, even sent more stuff for the saw after I paid. Manuals, files, Stihl CDROM, Chains, bars, oil etc.
