I'll clean it up it was dusty in the box weird.

Using my fingers to give you all a idea of how thick the piston skirts are way thicker than any that I've ever gotten from them in the past.

Where the ink pin is pointing a good amount of material right there that's on the intake side of the piston quite a bit more compared to the exhaust side now did they do that because of that's where the ring location pins are there or for balance of the piston going up and down to reduce piston Rock?

Any guesses on what brand piston this thing is.

But we don’t know how thick your fingers are lol

Bigger than a babysitter arm.

Ketchup is correct ft there piston skirts are normally pretty thin but not this piston.

Won't be using this piston in this saw at least not with the cylinder that's on it.

So after running my 372 clone side by side with the 365 with the big bore both saws ported by me obviously I'm going to be putting a 50mm top end on the 365 all tho it runs very consistent and very well but so does the 372 and it has way more grunt than the 365 with the big bore.

Do you have a picture of the just from the side. Did you drop the cylinder walls into half moon shape or is the angle of the picture just distorted

Ok my wife does love me she gave me my birthday present early because of bad weather and I don't want to use my clone 372xp right yet so she got me the clone 365 it is a open port version with the square intake manifold boot since I already had a 52mm big bore kit that I already ported and had on standby for the 372 I went ahead and put it on the 365 had to borrow the intake boot from the 372xp I just order another one when I buy a pop up piston for the big bore though I'd never say that but without base gasket the squish is right at .039-.040 yuck I haven't tried running it yet but will tomorrow I went ahead and did a compression test on it and it's putting out 140psi I'll check it again after I run it in if it jumps up to 170psi I'll leave it as is but if not a pop up piston will be going in like to see most of the saws I build to at least have 170-180psi some times more depending on what the saw is being used for I'm not going to be posting port timing numbers until I see what it got for power then I will share lol well ill share this much exhaust is 101 that's ok I would prefer 103- or-105 for using 32" guide bar and chain but anyway here's some pics ill post the picks of the timing after i run the saw . Oh almost forgot I did advanced the ignition timing 3/4 of the key. WE'LL SHALL SEE HOW THIS THING GOES.

I thought I'd post my own experience with a Farmertec 372XP kit saw from HL Supply:
Mine has very few OEM parts except for the air filter cover, small end rod and clutch bearings and a NIB Walbro HD12-1 carb. Just wanted to mention that the Walbro carb was well worth the $90 entry fee. With the poor quality control of the aftermarket clone carbs, I consider this a necessity. Just my opinion but I'm stickin' to it...
Other options were a Hyway Titanikel big-bore, pop-up piston, cylinder and Caber ring combo from Wolf Creek Saw Shop and An Exile Performance dual-port muffler. I did not port the cylinder but just did a little mild clean up work. It already looked pretty good except for a few dingleberries. I did a base gasket delete and ended up with about .020 squish. It has a ton of compression (cylinder pressure actually)! Not sure what it is since I haven't checked it yet but you pretty much have to use the compression release to start it. On the 3rd or 4th pull cold, every time by the way. I run VP 50:1 and the cylinder, piston skirt, piston crown and spark plug look absolutely perfect. I tuned the carb very carefully. With a 24" full-chisel full-comp oregon chain it's a wood eatin' monster! A lot of fun to build and run!

P.S.
These pictures don't show it but it now has a Red Beard's intake elbow and filter system along with an OEM Husqvarna tall filter cover. I've decaled it to look like a real 365XP just for S____s and g_____s. It's already fooled a few people! Lol
Also, cylinder pressure is just under 200psi...

Sorry for the really late response on the big bore I'd did something different from everyone else on the lowers because of case compression it works really well I figured if it works for a OEM xpw then it should on a 52mm now on my clone 372 50mm that cylinder I did open the lowers up quite a bit more than I would normally want to buy that saw is a completely different animal I did a few things different with that saw and so far both saws are running strong the 372 gets used a lot more because I'm always making little changes to it now I'm at the point with it to where I don't want to go any further with it I use them to clear blowe downs on the property so they don't need to be race saws lol
