first time portin...

Not sure on how far it needs to go? Depends on your specific saw..what you did and the altitude. No one will be able to answer that question I don't think. But I think 3/4 is an extreme adjustment

 

Thank you fur your input...yah...I was gettin pretty worried last nite when I was try to get it runnin...I have changed cranks and pistons before...but never modded a jug before...plus they where all used parts by at least two seasons...lol...hope it makes it thru at least a couple of tanks...thank you and god bless you...

 

Thank you fur your input Clem...true...I will play with it in an hour or so...you are runnin 32:1 on a mod saw...thank you...

 

I am running 32:1 on saws with just a muffler mod. Plenty of folks running 32:1 on ported saws. Like many of them.

I run modern saws too. Husky 372 and stihl ms650 are my main saws.

 

(I had to edit.)

FWIW, I'm running 40:1 in my rebuilt saws. Amsoil. It's more expensive. But, I run them daily and I like to take care of them. I love running hard cutting chainsaws. UURR, UURRRR, UUURRRRRR. God Bless men.

 

At the moment I am running amsoil. I have run bailey's syn oil also and several brands of semisyn.

Next I will run Lucas as I have heard good things although it's only semi. It's easier to get and cheap @$10/qt

 

Thank you fur your input Clem...on husky stockers...arnt yah suppose to run them at 50:1...thank you...

 

Thanks fire input Clem...10. A Qt. damm...can't afoard that... Lol...I'm a poor chaiser...lol...thank you...

 

If you want to follow what the manual says which they are leaned on pretty heavy by the EPA to meet regulations which effects the ratio they recommend for emissions.

EPA does not care one bit about the oil on your saws internals.

 

$10/qt is cheaper than buying those tiny xp bottles at Lowe's or the dealer!

 

Now if your buying bottom of the barrel El cheapo no name oil for $0.99 a gallon 50:1 mix bottle you may be cheaper...then again maybe that's why you had all those deposits in your saw? Mine don't look like that inside! And I think those bottle are still more that the lucus. There is 5 of those tiny bottle in a pint or 10 in a qt which is the same price as the lucus and you get a better oil.

 

Thank you fur you input Clem...this is what I have been runnin...is epa smog control...thank you...

 

There's your problem your using a water cooled oil in air cooled stuff. It's not designed to operate at the high Temps a saw sees. That's designed for outboards that are water cooled and run way cooler so the oil is formulated differently. Your not getting the lubrication you need out of That and possible why you have some of the deposits you do. It's better than nothing and I would use it in a pinch but that is not recommended for your saw.

And yes the epa controls emissions on saws which basically is smog control.

 

Thank you fur your input Clem... I got it tuned the best I can fur now...when the funds start rollin comein in...I will change my mix...what do you recomend...that's fairly cheap...is there carbs that I can use on thease 372 that are not epa...dose a epa have less performance than a non epa carb...thank you...

 

Use the same carb but just set it richer. Until you go crazy with porting I don't think you need to swap carbs. I'm no expert though. That is good oil...for a boat. I use it in all my outboards. And add to my tractor diesel as well.

You can get the Walmart air cooled two stroke oil. Look in the air cooled section of the oil isle. It's in the bottle with the little squeeze mixer on ThE top to add the right amout. It's not that much more I don't think.

 

If walmart has the poulan oil it's better than the super tech.

 

Top of the mornin friends...when hoggin the exhaust port on the cylinder side...do you square up the oval... Thank you...

 

You want to keep a nice arch for the rings.

 

Thank you fur your input redfin...at the ends of the openin...do I square those up...or do you just do that on the intake... Thank you....

 

Anywhere the rings ride you want to keep a round transition.
