IT IS STRONG!!!
I did a video today, but unfortunately I'm unable to post it. When I transfer it to my computer it says "format we don't support". Don't know what the heck is going on, but seems to happen recently if I don't have the phone horizontal (instead of vertical).
Anyway, the saw has less than 1/2 tank of fuel through it, but I decided to give it a test. With an 8 pin rim and 24" B&C I put it in some Hickory. It made the cut about 14% faster than my strongest running ported 77 cc saws, and they run very well.
For a Chinese kit I put togher, with the Cross MMWS P&C (w/o any addl port work), I'm very impressed, and it should get even stronger as I run it more.
It kicked on the 2nd or 3rd pull with the dcomp pressed (choke on), and started 2 pulls later (choke off).
Also, as mentioned above, when it was warm it re started with one pull NOT using the decomp. Just took up the slack, and pulled hard.
I think I'm gonna like this saw!
I will try to get a video I can post, this is very frustrating!
