lean the carb out, theres a screw where the two lines enter... run 50:1 with a synthetic oil... the mileage sucks on those engines, though.
Engine oil problems!

My little 31cc is running terrible and makes a 1 foot wide puddle of unburnt gas. Unless it does this, don't worry.

Wow, it amazes me how many people get into this hobby without knowing jack about engines, let alone 2 stroke engines. I would think that if someone was getting into this, they would know or want to know what they are dealing with as far as the engine, how it works, fuel-oil ratios, tuning, and the common things that go on with these things.
One of the first things I always see is complaints about these little engines, but the thing is, they are CHEAP engines. They will never be as good as a high quality 2 stroke engine (like on a Yamaha dirt bike, chainsaw or weedeater). These engines are cheaply made with cheap parts. They usually will never run perfect right out of the box, you will always have to tune and adjust things to get them to run the best that they can. (no matter who makes the engine).
A lot of people complain that the engines are junk because they don't run right, have low power, spit oil out the exhaust, spit gas and oil out of the carb into the air filter, bolts breaking, nuts stripping, etc. I think the majority of these problems is because of poor installation on the bike builders part. The other part is tuning, take the time and get to know how to tune the carb and you will be much happier. Take your time and install the engine with high quality nuts and bolts, with loc-tite. Make sure everything is adjusted right BEFORE you try to ride it. Also, go through the bike itself, check the bearings, brakes, wheels, tires and make sure the bike itself is working and put together right before you even mount an engine on it.
Do some research and find the most common complaints about these engines, and you will soon learn that a lot of these things can be corrected if you take the time to learn how to do it.
Think about it, you are getting a complete kit to put an engine on a bike for less than $200.00. A high quality 2 stroke engine will set you back far more than that, and that's just for the engine.
So unless you are unwilling or not knowledgeable enough to get an engine running right and tuned right, this may not be a hobby for you. ("you" in general, not you specifically).
One other thing I'd like to add is that yes, there are lemons when it comes to these engines, and some people do get them. Not every engine can be fixed, and is just a bad engine from the beginning.
I can't speak on behaf of engines other than the Happy times style that are made for bikes, because I don't have any experience messing with the other style engines (rack mounts, 4 strokes, or electric). I am talking about 2 stroke engines that are specifically manufactured to go on bicycles.
sorry, just my opinion.

I can do it, I have a very long tongue.
