Happy carving. :D
Whoooo - Hooo!!!
:thyel: The 3120 is an excellent saw. I had two (one on each end of a 60" bar for slabbing) and they didn't cough once in over four years.
let me know when you cook it. it wont be long
I ran my 3120 for a couple of 100's of hours in the Weipa area up on Cape York, doesnt get much hotter. I never had a problem with mine, except a bit hard to start on the real scorching days.
I did see 2 other guys melt the piston on their saws, both had the muffler come loose and they didnt do anything about it, so I put the failures down to that.
I always checked the tension on the muffler nuts when I cleaned my saw at the end of the day, I never had a problem.
I also ran my saw at 25:1 with good quality synthetic 2 stroke oil and premium unleaded, that may have helped as well. I pulled my saws engine down after about 100 hours of use, with the intension of replacing the rings. The piston, rings and bore were spotless, the old rings had the same gap as the new ones in the bore, so the old ones went back in, I still have the new rings in the shed somewhere.
My advise is, look after your saw, and it will look after you.
hey bud ,just because you cooked yours that don't mean I will ..Ive seen plenty of stihls get cooked and pistons explode ...its just the way we look after them, and being a stihl fan yourself ,you probably wanted it to cook so ya could bag it out ...haha:qQuote:

hey bob ..just one tank of 20:1 under load & idoling the Mix threw, for running in purposes (that's actually the ratio the dealer put in and recommended for run in). She's not running lean at all ,she's four stroking!! when talking around 1 to 2% more oil per liter its really not an issue (non EPA saws have a wide window for ratio's, being there based on the Jungle version) ...but I'll be using 25:1 after this tank ...and that is what the dealer recommends after run in and everyone else around here are using in there Big bore saws, Ive always used that ratio without any trouble too. I know you'll disagree with it ,LOL and so will the yanks ...but yeah :rolleyes: ...If she's not four stroking ill just ream the jet a little ...gonna open up the baffle after i run it in anyways, and Ill see if i need to ream the jet then ...but I Know the song a saw sings, so there's no worries bud. I never run a saw on the lean side ... The dealer even stated that when opening up the muffler on the 3120 ,the saw is still rich enough to four stroke without changing up a jet size ...I'm guessing the Aussie 3120 has a bigger jet than the EPA saws from the states. Aussie stock 3120's are basically a jungle version, without the opened up muffler ...cheersQuote:

Yeah I think it has a 1.2 versus a 1.0 mm jet.Quote:

You might want to read this arboristsite thread about the joys and pains of tuning a modded 3120.

I agree they love their RPM but work saws gotta last the distance so modding the crap out of them is not really the way to go.Quote:

I find the stock saws are just fine ..the 3120 and 880 in Aussie stock are brutal powerhouses ,bucket loads of grunt and bullet proof if cared for properly.Quote:
