I don't know the age of this machine, but more and more of the newer units are using a 50:1 mix to satisfy the newest EPA emissions regulations. I suggest using a synthetic or synthetic blend of 2 stroke oil. ....the big box stores sell the oil...Echo one of the best. I would use synthetic and mix it 40:1. Here is a fuel mix chart to show you how many ounces of oil in a gallon of gas that is. If you make a 1/2 gallon batch of fuel mix, just use half of the listed oil amount for the mix.
40:1 is 3.2 ounces of oil in a gallon of gas...or 1.6 ounces of oil in a half-gallon of gas

I have just spent a couple of hours on this.
You obviously have to dismantle the thing and get the plastic chassis off the engine so you can get at both sides of the gear.
The clutch has a bolt through it that threads into the gear. It's about 1 inch long. There are two holes in the clutch one of which you can line up with the bearing retaining screw hole. There is a small flat on the end of the gear you can put an open-ended spanner on to unscrew it. It is a normal thread.
Okay in theory.
I broke the flat off the end of the gear using mole grips. I did not know what I was doing anyway because there are no success stories that I could find on the internet.
As I was not sure how it was put together, if it was pressed on or threaded on, and which direction the thread went, I ground the end of the gear down with a 4 1/2" angle grinder and only did a small amount of superficial damage to the rest of the chassis, then knocked it through the bearing and then found out that it unscrews!
If you have to resort to this, I tapped the clutch down using a large socket (and a hammer) until it was tight against the casting and then turned it over and knocked the bearing (with the aid of a suitably sized socket) back to expose a small amount of the shaft so I could grind all the teeth off and not leave a shoulder. I also tapered it which made it easier once it started to move.
I hope this helps!
