That 4000 has serious power, it runs more like a good 70+cc saw.

I love the looks I get from those whom get owned by my lowly Craftsman 5.2. If ever, a single look could say "That's not supposed to happen!, that look would be it.

So here it is in its current state. I plan to have Nik mill an additional .014" of the cylinder base Saturday for some more compression. I also plan to throw a new set of rings in it just to see. The saw is currently tuned to 13,300.

Cut times with the same chipper chain I ran the stock times with are down 23% over stock. Once I threw a Stihl RSC chisel chain on it, they came down another 31%. With the port work and chain swap, it's now 47% faster than it was when I got it!

Here's the stock video again for reference. I captured the cut times from the uneditted version where I can see the chain touch the wood.

Wow. I had brad send me this link, since I am the proud new owner of a 4000. Thats awesome:clap:
 
Brad I'd be hesitant to run it at more than 12,000. I never set HI needle less that 3/4 turn from closed. Guess I scared of frying top end. As far as ring end gap NIk and I had a conversation about this. Rings are blunt ended and butt up to ring pin. Dia. of ring pin is about .060 thus wouldn't effective ring gap be less than the .125 you measured?
Bob

BTW Great looking saw!!!!
 
Those vids are from before we put a popup piston and new rings in it and did additional port work to it. It was significantly stronger than that when I got done with it. This saw will shortly be headed to Hawaii. I traded it for that beautiful table:clap:
