Hey, to all that use the great and powerful mccullogh's, the mixture on almost all of these saw are 40:1. Plus I put a little octane boost to help with better ignition. Hope this helps Scott @ Yahoo.com
1 oil to 40 gas.
Choose your oil; it is either 40:1 or 50:1 depending on that.
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.

25 to 1 is the mixture for the fuel

Answering "Where is the fuel mixture selonide on a 1990Isuzu Pup?"
The fuel mixture is controlled by the computer and is not adjustable.
50 : 1 is the correct fuel mixture
The fuel mixture for a Stihl chain saw is gas and oil.
It ignites the compressed air/fuel mixture.
