You can say it kills more than just cactus

Someone mistook chemicals for oil? Lol some chemicals are pretty thick. That's fughin special

It is not just the ethanol in the new gas, it is also the lack of lead in the new gas. Lead is a lubricant, so 50:1 with leaded gas was not so bad, but now the lead is gone, so I run 40:1 w/o any problems.

I'm really looking forward to having one of these cylinders on my saw!

I put one on a 660 last night. The flywheel side crank seal had a slow leak, so I ordered a set of seals for it. Once all tests pass, it is on to the test cuts!

For these kits, still want to use OEM wrist pin bearing, circlip, and do use a base gasket, ??? The thin base gasket??

Need to check squish on these??( I know that answer)

After market wrist pin Ok??


Just thinking out loud here!!

I was looking at the kit yesterday. I'd rather use the OEM pin and clips.

LMFAO

 

[Stihl working Hard]

Gotta watch for sure, but I had jobs as a temporary worker putting made in USA stickers over made in China on the label, and putting Chinese parts into a made in America bin!!!

Customs caught one company, that wasn't very much fun

That's not good misleading the consumer I know it's not your fault but even still

I have noticed all of the top end kits from HL Supply have 40:1 stickers on them now

Mastermind recommendation. Just started doing it last month. So yesterday a guy who bought some cylinders called and said he won't use it if he can't use 50:1. He wanted an explanation of why it say 40:1 when all his other Stihl's use 50:1.

 

[MustangMike]

It is literally "criminal" behavior.

Sometimes, you just can't win! Just tell him it is "recommended" based on the additional performance gains. That may help.

Do the AM clips break easier? Not have enough spring?

I thought I remember reading somewhere that Stihl recommends mixing 25:1 if you are not using their oil.
I this true?

A lot of the aftermarket components aren't hardened or finished as well as OEM. This includes the wrist pins, clips, needle bearings, etc. This can even extend to the tang on Stihl oil pump worm gears, pump pistons in aftermarket oil pumps, etc. There's a fine line on which aftermarket parts are great as replacement parts and which do not have the service life of OEM parts.

I learned all this the hard way when Bailey's started their aftermarket runs of parts back in 2003/04. I started as a test subject for the big bore kits during development and then for other parts as they started hitting the shelves. The aftermarket is getting better but it'll be a while before they catch up to OEM on certain things.

They have too much excess tang, and I don't trust them to be true spring steel.

On the wrist pin, weight is the reason I would rather use OEM. Look at OEM vs any aftermarket on the Stihl pins. The Stihl pin is bored on a taper from each end, and is quite a lot lighter.

In the older books I believe that's what I remember. The new ones just say Stihl 50:1 or equivalent high- quality oils. Maybe someone else remembers

That used to be true with several brands, including Stihl - I don't know if it still is.

Total BS of course, provided high quality (or same quality really) oil is used. What it really meant (means?) is that oil quality matters.

Have said "performance gains" really been proven to be the norm with stock kits?

If I had that problem, I wouldn't even trust me self...
