green machine back pack blower help

[deereman75]

I have a green machine backpack blower that I bought for $40 and it overheats and stalls after running for 10 minutes or more. I know that it is doing this due to it running too lean and i just have to adjust the carb. But i can't find any place on the carb to adjust it, there are no screws on it anywhere. I am wondering if anyone can tell me how to adjust it or if you even can.

What is the clue that it is overheating?
What is the fuel to oil ratio you are using?

Highly likely there is no carb adjustment. That is due to CA and EPA taking control of our lives.

I can tell it is over heating as the power is slowly decreasing as it runs and when it finally cuts out it way hotter then any of the other 2 strokes i have ran/fixed (a lot).

It called for a 20:1 mix of oil and gas and that is what i have in it, I also found out it is running too lean as i first ran it with 50:1 based on the recommendations of a mechanic I know, and it cut out way faster from over heating on that mix.
