Proper gas/oil mix for old Stihl saws

[cwatkin]

I just came upon two vintage Stihl saws and was wondering what mix ratio these called for. One is an 032 AV and the other is an 041AV Electronic. These are definitely older by their styling and the fact that they are solid metal. They also say "Made in West Germany". Anyway, the engines still have compression and both will run if you dump gas right into the intake. I am sure that these both need carb work but could be made to run normally. I am not sure if I am going to keep them as a shelf decoration, trade them off as is, or fix them and keep them around/possibly trade them.

Anyway, what mix ratio should be used in these old relics? I figure it wasn't 50:1 when these were made but will they work fine with modern oils at that ratio? I usually mix rich 40:1 on all my stuff and have no problems. I also use the Stihl HP Ultra white or silver bottle synthetic mix.

Thanks,

Conor

You'll be fine with your normal mix that you use in your other saws. The change in ratios over the years has more to do with the quality of oils as anything. I run the same mix in all my saws regardless of vintage with no problems. The key in my mind is quality mix, fresh petro and run the saws to keep 'em lubed.

Hey Conor, Just use the mix you normally use. They will be fine. Actually when those saws were in their heyday, the oil from Stihl was mixed at the same ratio. I would get them running if possible before selling them. But for my money nothing in 60CC will ever be better than your 041. They were very, very good saws. They didn't rev like new saws, but had power by the hour. Yes, a little heavy, AV not as good as new saws, but dependable. Try it, you"ll like it!

reagrdless of how old or new they are all of ours run 25:1, never had 1 problem with any 2 strokes we've owned.

25:1,,,,,,??? Really? Hmm, must be a misprint.

Any saw with a chromed or nikasiled bore regardless of age should do fine with the newer mixes at 50:1 or 40:1. I am not sure about the really old saws with cast iron bore liners.

No misprint.

Owners Manual -041 AV electronic

The manual said to use a high quality snowmobile oil with a mixture of 25 to one. It also said to use regular gas. Not unleaded.

Before trying to start up my old saw , I also wanted to check on what I should do. The 041 AV electronic was originally purchased May 1977 but has sat for over 6years and probably longer.

Thank you for all the advice that I have been reading.

When buying a new fuel cap for my '63 08, I asked this very question to the dealer, who has been around since my saw was new. The reply: "Some time in the early nineties, stihl issued a bulletin recommending the use of 50:1 stihl oil in ALL off their previously manufactured power equipment." So that is how I run all of my equipment. I'll bet some of the members here have seen that bulletin and could post it.

Oils are better now. A 40:1 to 50:1 ratio is fine.

Leaded fuel provided a cheap octane boost, and "cushioned" valves as they seated, 40 years ago. Two strokes have no need for leaded, since they don't have valves.

You're lucky though, since you live in BC. You can fuel your saw with high octane, ethanol free, gasoline. Any Shell or Chevron high test will be what you want to fuel with... No ethanol.

Thank you for your help. Now the next stage for me is to see if I can get it running as it has sat for a long time.

Thank you again

Back then it called for 40:1 ratio the main thing is use 93 octane fuel with no ethanol and a good full synthetic 2 cycle oil a lot people confuse that with a

Back then it called for 40:1 ratio the main thing is use 93 octane fuel with no ethanol and a good full synthetic 2 cycle oil some old timers would do a 32:1 with there carbs tuned but I would do factory specs unless has been modified ported or hot saw but that's a different story a hot saw and work saw are like day and night but back to the topic if you are interested in trading I have several full rebuilds with pics and I use all oem parts sometimes takes me months to find 100% stihl parts not saying anything wrong with aftermarket and there are a lot of knockoffs parts also got to know what your looking for let me know if you want to horse trade I rebuild these old dinosaurs for a hobby so I take my time and do them right but you will have a saw that cut with the best of them I have a little old 028 av wood boss I would put up against any new saw but I done a full rebuild from the ground up man she is sweet if interested hit me up will let you know what I have.
