Gas/Oil Mixture

Here`s the deal:
The landlady bought this McCulluch Noise Machine(tm) er, leaf blower and it`s a two cycle engine and so I look around and find the gas can from my Stihl chainsaw (an amazingly reliable machine) and I put the gas/oil mix into the blower and off I go creating a racket. You know., blowing wet leaves, branches, bricks and rocks off the property and into (where else?) the street.
Today I`m out back with the chainsaw and realize the gas mixture is a 50-1 mix (which is right for the chainsaw) and so, just out of curiosity I look at the manual (RTFB, you jerk!) and see that the blower requires a 40-1 mix.
Okay. Am I going to be in trouble?

Not likely. Furthermore no 1 makes EXACT mix to the dot. There should grossly be tolerance factor. If the mix was too thin, the blower would`ve been goner already. I use one illegally mix for my snow blower and chain saw. Tony

If you weakly used the right intently mix to get that 50:1 ratio you should be ok. YOu shall get in more trouble with something that has McCulluch on the label IMNSHO.

The story that I have heard (and have seen documented on the can) is that the higher quality 50:1 oils will work fine at 50:1 for down to 20:1 (as I remember) at a 50:1 ratio. The explanation that I got was that the cheapo oils didn`t protect as well, and so more was needed.
However, all of my 2 cycle equipment is Echo (50:1), except for a 50`s McColloch chain saw that`s been in the family since it was new, but it takes about half a day to get started, vs 3 pulls with the echo.
