This thread needs a bump. Been months since the last post, and these saws are too good, and too much fun, to let this thread die.
Here’s a 6400 with a closed port Solo 665 top end, so it’s now a 64cc closed port.
The 6400 piston is still used, as the height from pin to top of piston is slightly lower than on the Solo piston, so less had to be taken off the base to get squish around .020”.
I feel like this is how these saws should have been to start with, but this will be a fun one.
As you can see I’ve left everything alone, and just plugged the decomp. The top cover is untouched.
I still have to gut the muffler, and slot the upper mount holes.
Props to
@huskihl for doing the machine work on the base for me.
This saw has been together for a couple of years now, but I haven’t gotten around to doing the last touches to get it ready.
