So my sisters eton vipers oil pump stopped working and I was wondering if anyone knew the fuel to oil ratio so that I could pre mix the fuel. I don't know the cc but it looks to be around 70cc. I ran it on 50:1 ( because I read that somewhere) for a few fuel tanks but it doesn't seem to like it so I was wondering if anyone else knew the proper ratio
- thanks

 

Those Linmax copies of Suzuki LT50s had a "use 32/1 ratio" sticker on them. I would expect a Chinese scooter engine to be similar.

 

No Suzuki copy here Merryman.
Eton is a finely made Tiawanese machine.
But 32:1 is correct.
