2 stroke or 4 stroke?

[Brad]

Hello. I just purchased this Ryobi weed trimmer off of eBay and I can't figure out if it's a 2 stroke or 4 stroke. No papers or manuals came with the trimmer. This is the info I can give you:
MODEL: RY30002A
SERIAL NUMBER: AH0341781
DISPLACEMENT: 30CC FAMILY - 4HCPS.0304AC

Thank you for any information you can give me!

Hi Brad,

Your trimmer has a 2-cycle motor. Remember to use "mixed" gasoline in it. That is gas with 2-cycle oil. The proper mix ratio is 40:1 or 40 parts gas to 1 part oil. Most 2-cycle oil is packaged in a 50:1 ratio size of 2.6oz of oil to a gallon of gas. To get the 40:1 mix ratio with a 2.6oz bottle of mix oil, use .8 gallons of gas.

I hope this helps!
