What's on your bench?

Been spending time cutting chambers and bases on muh lathe. Squish between 17-22 on all of these at this point. If I could only find the time to grind.

China 440....

Im investigating the e clip clearance issue...and I found this....

Oiler pinion nearly put a hole in the oil line.... ugh.

372 XT belongs to a local logger, ate the crankshaft. Was able to get a good used crank from another member and rebuilt as a 50mm XP.

Full circle crank in a 288?

No Sir.

Friend owns a tree service and backed over 540 with Cat Backhoe. Picked up other 540 from local junk pile, no compression, straight gassed. Waiting for new ring and gasket. Hope to make one running 540 out of two. Gives a different meaning to bucket saw. 540's are his most used saws, then 562's, 576's and 394.

China 440 on the bench.

I think huztl put the wrong bearing on the pto side. It's too thick....10mm inner race vs 9mm. Hopefully this solves the e clip mystery.

Swapped out the farmertech top end for hyway...and did a little poor man's porting on it. Didn't need much unlike the ft. Simple base gasket delete and some reshaping of the ports. Transfers were weird.....fixed. timing at 100 115 79

@Mastermind

MM,

do you have a junk oem 044 pto bearing sitting around? can you measure the inner race depth/thickness ... whatever. is it 9mm or 10mm?

Had this oleo mac on the bench, just needed a really good clean and two missing bolts replaced. Made up a couple of adapters out of 8mm nuts so I can run my Stihl bars.

What killed this saw???

Pressure test ok. Gas is blue.

Ran 2 hours...then scored. Bolts tight. Base gasket pulled in half when I removed the head.

Is the intake boot thingy warped enough to cause a leak??

Why the score to one side of the head?

 

[dall]

Looks like ran too lean

 

[CJ Brown]

Transfer tunnels look really dark - too little blowdown?

 

[Mattyo]

Hardly any wash on the piston head...

Pretty sure it's lean sieze.....but why is the question
