Oh dang!! Never get snow like that here. Haven't had any snow in over 3 years.

I've never had a saw that would turn 15000 but I've never ran a 346 either.
17k is race saw territory I think.

My stock 440 4 strokes at 15,500 with a healthy muff mod, ported 460 at 16,000 and my 390 has been putting out 16,000 when I've cut with it (still burbling hard).

As for his video and piss revving? It was cold saw.. I only piss Rev on a video when the saw was pre warmed.

To piss Rev a saw at top rpm on a cold jug/piston?? Well, you might as well give the saw to me before you scrap it... Best practice is to bring the saw to operating temperature

 

[DexterDay]

And to the OP... Sounds like your happy!!

Nice saw! Congrats!

What a great thread.

And Randy's the principal now.

That's what I'm talking about!!! No More F_ _ _kin crybabies

I've got like the mechanic who won't work on ford's anymore, I turn down most every saw that isn't a 1122, I'll do 394/5s but I don't like many of the new saws, takes to big a box to hold the parts.

That ain't no lie!!!

1. I was joking.
2. I watched the official video from Stihl that shows how to properly start a saw, and the guy in the video piss-revved the living *s-word out of it right after startup.
3. Jonathan and Jeremy like turtles, and Mastermind likes pie.

Repped, hard....with extra piss.

I'm a huge piss revving enthusiast but I like them warmed a little before I let the trigger have it.

I kicked up an 066 one day to drain the fuel from the carb and fuel lines before it was pulled apart and quickly realised it had no exhaust bolted on

Don't they make some noise when you rev them with no muffler.

Watching....

I'm finding that Richer is better in the wood. Cuts faster and saw stronger.

I need to get over the chest pounding, or lack thereof, of my tach readings.

My Masterminded 066 4 strokes at 15k. I'm running a 28" in .404 on it.

The saw has loads more grunt when richened up to 12K.

Depending on what bar I have on my 66 is how I tune mine. If it's wearing the 36" I've found that 13,200 is its sweet spot. Shorter bars get 13,800 to 14,200, but that's about as far as I go

 

[drf256]

Yup. You know what I'm talking about. Depends on the load placed on the saw. I was noodling 24" pieces of Sugar maple all day. I could bog the saw down with the dawgs fairly easily when tuned in the 14's. It was a brute at around 12k.

I think my rakers were at .050. I was told that's standard for Stihl RS in .404.

 

[Deets066]

I think off the roll is .030?

.050 is low takes a good saw to noodle with that

Rslf 404 063 is .018, .050 is very low

 

[Brewz]

I run my 404 at .030
I have found my 066 runs best in wood between 12 and 13K no load.

RPM's doesn't always mean torque, which is what you are after with a big saw in big timber

I bet its pretty aggressive even at .030?

 

[Brewz]

on a 25" bar it works well.
Its a bit bunpy in the cut but dont it smash through hardwood like its going out of fasion

Have u went any farther down on the rakers to see where it was too much?

 

[drf256]

I bought my bar and chain off redbull661. He told me whatever I have was .050.

It was grabby, to say the least.

Yeah, my MM066 is ballsy.
