cliffreaves,

I bid that up to the $500 mark, that was as far as I wanted to gamble on his description of the saw. Plus, I don't trust others mechanical work, especially on big bore kits. For that price, you can do some rebuilding if she blows :D I'd run a synthetic 40:1 while milling with that saw. Fouled spark plugs are cheaper than top ends and down time. Good luck with the saw, let us know how it runs!

I can't say I completely understand the concept of gas to oil ratio, but it seems like 100:1 would more likely blow the engine. 40:1 sounds much safer to me. I don't know why he would tell me 100:1.

Some synthetics claim that they can run at 100:1 and maintain lubrication, but I've always leaned on the side of safety and run synthetic as the same blend as conventional. Oil is cheap compared to repairs in the long run in my opinion.

Alright guys, I got the saw in today and the first thing I did was remove the muffler and check the piston. I was amazed at how clean it was, no scoring at all looked brand new. I bought a replacement air filter cover that came in at the same time as the saw and I fit perfectly. I contacted the seller and told him thank you and that everything looked great. He said the top end only has 1 hour of use on it, so pretty much a new saw. I'll get a chance to actually fire it up in a couple days. should I treat it like a new saw?

Yep that top end still needs to be broke in.

I'm running the echo synthetic blend with 92 unleaded ethanol free fuel. I took down a 30" walnut, limbed and bucked it today. The only problem I had saw wise was the chain and bar kept getting really hot. I was running a 24" bar with the oiler turned all the way up. The chain is sharp and making good size chips. There was definitely enough oil coming off the end of the bar. Any thoughts on what I'm doing wrong? The bar and chain were only smoking in stuff that was about 15" or more. The saw is a beast!

What kind of bar oil are you using. I would use a heavy grade chain oil in hardwood. Check your nose sprocket make sure it turns easy. Also make sure you bar is not full of chipps that will soak up the oil and keep it from flowing to the bottom. Check that you chain is not to tight in the bar grove it could be the wrong gage of chain or a pinched bar.

If you are seeing smoke it could be a clutch problem too

I would make sure ,you don't have the chain to tight . You should be able to pull it around the bar easily .

Alright, finally got the chance the run the 395 again between storms. I checked and deburred the bar, sharpened the chain and, cleaned everything really well. I didn't see a bit of smoke while running it this time. I must've just had the chain too tight. The burs on the bar didn't seem bad at all but that could've contributed. Either way, it's fixed for now. Thanks again for the help!
