Look for the bolts
If using an oil other than McCulloch, the ratio is 40:1. Brand Specific McCulloch two cycle oil is 20:1.
1982....wrong First Mcculloch 10-10 came out in 1967. First Mac -10 series saw was in 1965.

40:1 with high quality 2-stroke oil mix would be fine. http://store.chainsawr.com/
50:1 is incorrect. That mixture will not allow enough compression and the unit will be very hard to start, if at all. That mixture works well for Sthil products. If using an oil other than McCulloch, the ratio is 40:1. Brand specific McCulloch two cycle oil is 20:1.
When came out it called for 16:1, but with todays fuels 32:1 mix of a good quality oil will suffice. Most 50:1 oils should work but get a name brand
16:1
Lossen the two bolts on the side of the chain bar, then use a straight screwdriver and straight under the chain turn the screw clockwise, don't tighten it to much, make sure it still turns, then tighten the bar bolts
I have owned a McCulloch Pro-mac 5000AV since 1996 and it has served me very well. I have paired this saw with a Husqvarna 55 (purchased in 1997) for significant woodcrew efforts (downing and cutting dead trees, cutting fallen trees, cutting delivered logs) over the last 13 years and both have been extremely reliable. Both saws have significant anti-vibration designs that work quite well. dwmobrien1@aol.com
