New to me, 390xp

[mdavlee]

Not even a stock saw Mike? Stock 390.

Nope. Most I torn down were stock runners to port. I’d run 40:1 minimum in every piece of OPE

I ported a 385xp muffler once in front of my 4 year old son, he found a stray bolt and later put it inside the muffler... I luckily heard it rattling before it got inside the cylinder

I ran my Stock Stihl 029 FB for over 20 years at 50:1. Piston and cylinder looked like new when I sold it. Mostly Stihl orange bottle.

50cc lower performance engine, also. It was probably tuned to 12 k and spent its life in wood at 8k. As opposed to being tuned to 14k and spending its life at 10 K in the wood

Yes Kevin. Thus my preface of a stock saw tuned correctly at 50:1

Lots of stock saws tune at 14 or 14,5k and run 10k in wood though. Could be why your stock 029 survived for so long and others spinning faster didn't

Cut a lot of wood with that bugger though. Just 1 saw. Then I came here and now I have many!!!! LOL

Oh I hear ya. My dad had an excavating business and had a few 039's. They ran pretty well for years unless they got run over, which happens with multiple employees

My 044 ran non synthetic 50:1 for years and it still runs great, but I run everything on 40:1 AMSOIL Saber now, just to be safe and now none of my saws are stock.

This site cost us alotta money Mike. Lol

32:1 for me, stock saws, ported saws, stock 250r, heavily modded 250r... All get 32:1

You guys are making nervous about my 390. I like that saw, its smooth with good power and easy on fuel for its size

Don’t overthink it. I cut about 15,000 bd feet on the landing today with a 562 on 50/1 and it’s just fine . I do however think saws benefit from more oil in the mix. They will be more “tolerant” of abuse such as subpar chains and blocked cylinder fins. I will be mentioning to my boss about the benefits of 40:1 the next time he fills his gas jug. Few extra cents gallon shouldn’t hurt anyone and you get better long term longevity. Keep the chain SHARP, clean the saw often, good mix gas/oil and saw will last a long time. Pretty simple really.

Joe,

Your intake skirt is fairly polished, I think it would be worthwhile to slap a new piston in it and see if the knock goes away. I think the knock in your saw sounds exactly like the one in Dave’s video a few pages back. His sounds more intense but I’d be willing to bet that’s because of how phones pick up sounds in videos. Next time you’re down here or I’m up there we should get a video of it running for comparison.

Could pull the cylinder and slip a feeler gauge in there to see. Certainly can't hurt. Normal so far for me has been .0015" (which seemed a little tight but ran well) to .004".

I was thinking about getting a vid as well.

Easy and cheap enough to toss a new Meteor in there. And if it doesn't cure it I'm really not out anything as I was planning to swap the piston out anyway

If youre talking about bucking them from tree length to log length, that's a pretty good days work! Just curious as to why youre bucking with a 562? LOL Im afraid to hand my guy on the yard a 562! I seriously doubt it would last a day with him bearing down on it. My "cut up" saw is either an ms461, 576xp or redmax gz7000 which is a 575xp painted red.

Yep tree length to log length. It’s a ported and as fast or faster than a stock 372. It zips good with a 20” bar and good chain. Not as much torque as a 390 lol, its only 60cc all things considered. But I like it so far in small/medium wood.

Your 562 is a very strong and fast saw. Runs real good! [emoji106]
Is it a Rattler?
