I was given a Homelite ST-200 20501-A string trimmer minus the manual, and I have no clue what the ratio for the fuel mix should be. Any ideas?

You can purchase some "super" mixing oil that is suppose to work on all ratio mixtures.

I use Opti2. I have had very good luck with it. I use it in my weedeater, also my outboard motor and any 2 cycle motor. I swear by it,

16:1 Ratio or 8oz of gas per gallon of gas.

Part no for manual is 17699-A.

These trimmers are 26 years old and parts are hard to find.

I need the size of the brushcutter blade this trimmer uses, not the tri-arc but the saw blade.
