New to milling

[Upland Keeper]

Hi .  I’m on milling a sycamore using a stihl 661 with a 42” LP bar with a panther mill. 
The log is taking the bar to the max .

Ive cut 3 slabs and on the 4th the saw cut out with a little to go .  
The saw wouldn’t start after that , I’m guessing flooded engine .  
It started ok the next day .

I finished my cut of the 4th slab and started 5th and it cut out again. I’m currently letting it sit , and cleaning and sharpening chains . 
I’m thinking about  servicing saw to see if that would help . Any help for a novice miller would greatly be appreciated.

thanks

How old is the 661. I'd guess it's siezed. And will run when cold but looses compression when hot and the pot has expanded. First thing I'd do is remove exhaust and inspect piston.

It’s 8 yr old,  I bought it of a fella who bought it from new it was just a bit heavy for what he wanted , I’ve not done much with it until now.

Thanks Bill

Make sure they don't just put another piston in it and call it that . If they don't find the cause you will be back here again . Just saying .
