Bought a Weedeater XT 20T at a yardsale. No owner's manual. Seller gave me no information.

So, is the engine a 2-stroke? If so, what is the oil/gas ratio?

Also, I need a gas cap. How much?

Thanks,

Wes

The oil to gas ratio for mostly all weedeaters is 40:1 and you could get a gas cap for 5 dollars brand new they aren't expensive
