Kioritz SRM 302 brushcutter oil mix?

[149owner]

This brushcutter was my father-in-law's and I have no manuals for it. I'd like to know what the fuel/oil ratio is. I couldn't find any info about it on the Echo site either. Does anyone know where I could get a manual? Thanks.

Have you considered one of the synthetic oils that cover a range of mixtures? Amsoil Saber 100:1 comes to mind.

or you could just run Echo oil mixed somewhere around 40:1. It's supposed to be mixed at 50:1 and should lubricate fine there, but if you just mix it a little heavier on oil I believe you'll be fine. The Echo oil is semi-syn and vastly superior to your typical 2 stroke oil on the market when that trimmer was new.

FWIW I run all of my 2 stroke equipment (Echo, Shindaiwa, Redmax, Dolmar) on Shindaiwa oil mixed at ~40:1 with premium gas.

I don't know what difference the addition of ADX might make to the model but did you try this:

I have a (currently broken) Kioritz Echo SRM-302 trimmer / brushcutter and with a cursory glance I can see no difference between the look of this one and mine.

I think That I may have the same.
On the housing it says Kioritz SMR 320A a 2 cycle oil gas mix a real pain in the *** but, I have to admit it still runs.Lucky, I guess.
which I believe it to be an ECHO
I was told that my model was 30-years old
Guess that's why I have to put cutting string on the head manually by cutting 2 equal lengths and feeding through head clip holders on the head.
I see you found a manual online. Is it very helpful?.
