Don't use stabil. Use a modern synthetic saw oil (50:1 fuel to oil ratio) available at home centers, hardware stores, and saw dealers. Mix the oil and fuel in it's own container and be sure to shake the container thoroughly just before filling the tank each time to prevent oil starvation. If it becomes apparent that the carburetor adjustments are wrong, you will need to see your dealer for adjustment. Good luck!
there normaly a 40-1 mix,,,i run mine in a 30-1 mix,, now i know your going to say "thats a bit ritch!" but my saw is 20 years old now? and i look at it this way,,,if you can see smoke you got oil?
if you run it on two stroke or engine oil you need to run it on the ritch side,,,so stick on 30-1
Macs run fine with 40:1 ratio. Be sure to use fresh fuel and a modern synthetic saw oil. Mix it in it's own can and be sure to shake thoroughly just before adding to the tank which prevents oil starvation. Don't make more than a gallon at a time unless your business is sawing. Hope this helps!
Quick check with mfg (DAGS mcculloch) yields: 40:1 with their 2-stroke oil and 87 octane. I've run one (with 14" bar) for years on same 50:1 mix I use in other saws with no problems- synthetic oil and regular gas. One of these saws is now 30 yrs.old. And ... no smoke-cloud, nor port/muffler mung. With new saw, you might want to use more oil for first few hours. Just remember that doing so leans the fuel mixture.
Most of the old Homelites were 32:1. I eliminated the mix problem for all my equipment when I started using a synthetic 2-cycle oil called OPTI-2. Somehow it works for all 2-cycle saws/trimmers/blowers etc. I've got equipment that's 20+ years old and still running strong with the OPTI-2.
Most saws built within the last 30 years or so can be run with 40:1 using modern synthetic saw oils. A number of late model units run 50:1. Make sure to premix the fuel and oil before adding to the saw. Hope this helps!
40:1 according to Mike Acres site, same as current recommended mix: Chain Saw Collectors Corner http://www.acresinternet.com/cscc.nsf/ed1d619968136da688256af40002b8f7/8f167f396637c29d88256c2e0073560e?OpenDocument Oil Mix Ratio: Dolmar, Echo, Efco, Homelite, Husqvarna, Jonsered, Makita, Oleo-Mac, Red Max, Ryobi, Shindaiwa, Solo, Stihl & Tanaka; all recommend 50:1. • 1 gallon of premium fuel to 2.6 ounces of quality 2-cycle oil. • 4 liters of premium fuel to 80 milliliters of quality 2-cycle oil. McCulloch & Poulan; recommend 40:1. • 1 gallon of premium fuel to 3.2 ounces of quality 2-cycle oil. • 4 liters of premium fuel to 100 milliliters of quality 2-cycle oil. Chinese chainsaws recommend 25:1.
McCulloch Manuals Operators Manuals: are much more difficult. I have dialed this number many times (Contact Us - All McCulloch Products 1 (800) 521-8559) and have yet to get a satisfactory response.

Use a quality 2 cycle oil and mix it to the OIL supplier's recommended ratio. Today I use Stihl 2 cycle oil mixed @ 50:1 in a Pioneer that I purchased new in 1980. There are no gouges or scratches on the piston or cylinder and I have no carbon build up on the piston top. The manual (on stone tablets) recommends 24:1. Over the years the mixture has leaned from 24:1 (Saw Recommendation) to 28:1 (Lawn boy mower recommendation) to 32:1 (Oil provider 8oz/2gal - used for many years) and finally the last 5 (±) years 50:1 (Stihl 2.6oz/1gal)
Any fuel containing ethanol is not good with chainsaws. Mix what you expect to use within a few months. Anything over 1.5 months old use up in a 4 cycle engine. HTH
