My 3/8 chain that is the right length is 103 drive links. Its really tight though so an inch or two longer chain would work.

My math is close. 103 drive links by pitch then divided by new pitch  |

If your current 3/8 chain is 103 drive links, and is a little to tight, I would go with 94 drive links of .404.

Id like semi skip, but i think it could handle full comp.
I almost exclusively cut hard woods so full chisel is ideal from what i understand.

HOLY COW. THIS SAW RIPS!
Seriously, I am shocked by how hard and strong this saw cuts. I had it BURIED in some green pen oak and it didnt notice.
It currently has a 24~ inch bar with full comp rounded tooth .404 chain and 8 tooth rim sprocket.
After an initial shake down it has some kinks to work out. The clutch is bound to the drum, which is likely caused by a washer behind the drum. Will confirm when I get back to my shop.
It also started acting like it was starving for fuel. I put new lines and a filter on it, but the tank was pretty dirty. I did an okay job cleaning it out.
My thoughts are it is either a bad filter or the diaphragm gave out. Will know more when I can tear into it and confirm.
At this point, I am going to fix those two problems, do a compression test and check squish now that its been ran, and then possibly a base gasket delete depending on those results. The reason I didnt this time was i completely forgot to get the proper sealant, and some smart fellows told me to run it and see what I had before i made any serious mods.
Anyhow, happy sawing!

Not an expert but you mention saw seemed as if it was starving for fuel and if i read right you have no base gasket or seal on cylinder head? Possibly a leak ?

I can tell you, being the first person to ever run that saw, it will pull a 36 in Red Oak and ask for more, Joe.

I suppose you guys deserve an update on the 1050 since you have been so much help getting it to this point. I have been able to get a couple of hours cutting with it and i have two major conclusions: I am not as much of a man as I used to be, and this is a whole lot of saw.
Once I got the new piston from Red Barn in and got it running it plugged up 2 or 3 fuel filters before it would stay running under load.
The clutch was bottoming out against the drum and oiler creating some other problems, so i changed the stack of washers on the clutch side and now its perfect.
I also checked compression and squish after a morning of cutting and compression was low, as in 135 psi (my gauge tends to read low on smaller saws). Squish was at least .130. So i took the jug back off to do a thorough examination to make sure my port fix was holding up and to make sure everything was working correctly, which it is. While it was off i did a base gasket delete bringing squish down to just under .100 which is still a lot. I measure this new piston against the OEM one and they are identical.
The saw runs good and hard, is a reliable cutter, and does its job. My thoughts at this point are two-fold. I did raise the ceiling of the exhaust port .010 and widened it to about 60% of the bore, so a lower compression reading is to be somewhat expected. However, do these saws leave that much room in the top end? Even without a base gasket, nearly .100 seems to be excessive.
If that's the case, i cant imagine how hard this saw would run if squish was down to .050 or so. Maybe I will have the jug decked over the summer?
