Daniel's advice is very good.

John, you will love those 2 engines!

I have of late been using 25 or 30 to one mixtures as of late. Many will run on 10 to 1 however sloppily.

Most of Jin's I have mixed with Marvel Mystery Oil and with some of my small ignitor engines I use a 25 to 40 to 1 Coleman fuel with 2 cycle oil.

Jin's spark plug ignitions work fine with Marvel Mystery Oil. You may occasionally want to remove a spark plug, clean, and dry it.

Jin's will run fine with 2 cycle oil. I could be just blowing smoke here however I have felt the Mystery Oil was better at protecting the O-rings on the pistons. He includes spares with the engines and after having my first one more than 10 years ago I learned quickly the O-ring likes to stay lubricated. Ever since I have never had to replace another O-ring.
