I tune every saw every time I use one. I don't think u necessarily need to but it's become habit for me. Haven't seized one in years either.

Perhaps I'm I'm seeing bigger temp changes day to day than you guys, and if Randy says a ported saw is more sensitive to that stuff (and he did), I believe him.

Besides, the last thing I want to be doing when I climbing over logs and going through the woods is to take my gloves off so I can tune my saw with a tiny F ing screw driver.

My 044 #2 seems to be a bit more sensitive to it than the other saws, but I really like the way that thing runs. Not quite as strong as the ported 77s, but close, and a whole lot lighter. With the 28" light bar, makes a nice nimble felling saw. Then I use the bigger guys for bucking. A 25" dead Elm gave them a nice workout today.

I love my hybrid as It balances and feels nimble also with the 28 es light. Mike you shouldnt need to adjust the high and low speed so much? I can see with a big temp. Change the idle needing alil at the start of cutting?

The saw has been idling just fine, just every now & then it either sounds too rich or too lean (at high speed). For example, it sounded a little rich today, did not clean up in small stuff, but ran well in the big stuff, so I left it alone. Just seems a little more sensitive to the temp changes than my other saws, but our temps have really been fluctuating. It can be in the 20s in the am, and in the 80s in the pm (the same day or a day later).

FYI, my 362 did real nice today bucking some 15" dead, dry Ash. It does not have the torque of the bigger saws, so I think running square file on it really helps.

That hybrid must be real nice, but I think you would also like 044#2, it is close. That saw has pulled that 28" bar real nice in both Oak and dead Elm.

I heard the hd2 filter and dualbport muffler cover mod makes a saw go in and out of tune ,has anyone else experienced this issue besides me ?

More bad poasting.

Ya big ole' dummy.

I tune mine fat and let them go. Rarely see a temperature change from day to day to change tune. Oils have made the biggest difference along with VP fuel. Some were 1/4 turn on the VP from 87 pump gas.

What are using for a hard line tach?

Is that a Tiny Tach?

Do u run 87 much? How does it do

 

[jmssaws]

I've always used 87 and never had any problems until my newest saw got to where it didn't like to die, switched to 93 and fixed that.

 

[MustangMike]

I heard the only cure was to triple port the muffler!

 

[MustangMike]

Another factor I should mention. Even though it says ZAMA on it, 044 #2 has an AM carb. That may be contributing to my problem, though it often runs just great with it.

All the time. Never had a problem with it on any saw. I have VP but at $16 a gallon it's used sparingly.

There's a VP fuel station close to me and they have 110 but also 89 and 93. I use the 93 now but the 110 sure smells good, 8$ a gallon though.

 

[Trx250r180]

I think it is 8 bucks a gallon where i get my oil also ,and at the bike shop .

Which VP do you use?

 

[mdavlee]

Which VP do you use?

94 octane gas. No 50:1 for me

50:1 is to lean to even wash parts in.
