why did my weed eater have hard starts up until I began to use small engine fuel?

I would usually mix my 2 cycle oil and gasoline (93 octane) and my weed eater had some really hard starts. When it would start a gray but clear smoke would be seen for  about 30 seconds and then disappear.

I decided to buy a premix oil+fuel called "Small Engine fuel" that they sale over the counter at hardware stores. It is usually in spray paint cans or small cans. 

I dumped the mix that I made in the weed eater and then put the small engine fuel into my weed eater. 

The hard starts disappeared instantly.

    The premixed small engine fuel is way more expensive than the gas/oil do it yourself mix, but if it can safely work in your weed eater, and eliminates the hard start issue ,use it.
