ProMac 850 is 82cc capacity motor & Fuel mix is 25:1 - especially now that we only have unleaded... best to use BP Ultra 98 octane as these saws were designed to run on Super leaded fuel. I used to own a 797 Super (123cc motor)

Fuel mix ratio for poulan counter vibe 3400 chain saw and for a homelite st-145 weed trimmer

Oil Mix Ratio: (last 5-10 years)
Dolmar, Echo, Efco, Homelite, Husqvarna, Jonsered, Makita, Oleo-Mac, Red Max, Ryobi, Shindaiwa, Solo, Spear & Jackson, 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 & Wen; 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.

If me I would have the Poulan tweaked to run properly on 50:1 and use that in both. It will start easier and take much longer to carbon foul.

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. Please try this! If enough of us try they will fix it! If unsuccessful with McCulloch try here:
Beg for manuals thread (ArboristSite - free to join). Please use the search function first, it has probably been asked and answered.
