80cc 2 stroke motor start and then just sputters out

I will make sure the spark plug is dry to

Ok one last thing on the carburetor to do before you Try and start it with choke on there’s a button on the carburetor that looks like a rivet but when you push down on it’s spring back that’s a gas primer . Give that a couple to 4 pushes .

The spark plug should be wet to show that it is indeed getting fuel,First few starts and maybe cold start's will require full choke (closed) to pull the fuel in, when it start's as suggested above pull in the clutch and see with no load if you can keep it running (may have to use throttle)if it's really rich,if not it should rev up with throttle input and drop down to idle when throttle is released.

yes I did no to prime it but thank you very much anything you suggest like that their Maybe something I don't know as I said I am new to Motors but I am getting ready to go down on try the three things we spoke of in just a moment I will update you

I know only what I have learned in this process as far as motor maintenance repair or installation I'm not quite sure what you mean by if it is rich by that do you mean the fuel, and not quite sure what you mean by with no load I'm slowly learning the technical jargon but as I said very new to the process I'm a quick learner though

so I still have to try starting it with the choke off in just a minute but kind of ran into an issue Friday I can buy a new spark plug either way but I cannot see good enough to see if a spark is coming off the plug that I have should the spark plug be all right where I did have them motor going for a few feet or should I just replace it Friday either way

and not sure if I'm supposed to but I smell gas when I unscrew the spark plug

That’s good you know the engine getting fuel ! The spark plug only has a small space for spark yes it hard to see spark. It would be easier if you had someone hold back tire up and spin the wheel as much as they could with spark plug in the wire lying on head then maybe you can see it then.

That’s good you know the engine getting fuel ?

okay I don't know if you saw the first thing I had posted should the spark plug be alright or should I just get a new one Friday I was thinking maybe it is okay since I had a going once but I can't see good enough to see if a spark is coming off of it

I am

Rich means too much fuel...
Lean means not enough fuel

As said,,, when you first starting the engine when its cold,,, the spark plug would be wet,,, a conditions of """Rich"""/ thats a good thing meaning that the engine is getting fuel...

When it warms up,,, we hope that it gets too a bit """lean'er""" / a more dry spark plug...

Rich with lots of fuel cold start up...

A dryer spark plug when warmed up,,, lean...

When you use the choke,,, it actually draws more fuel into the engine,,, """rich in fuel""" helping the engine start...

Too much choke will flood the engine with too much fuel... the engine won't start when its flooded...

A way to de-flood the engines is too turn fuel off,,, get the fuel mixture out of the fuel line and carburetor,,, take the spark plug out,,, then pedal your bike with engine spinning,,, you won't have to go very far too vent the engine,,, a 50 yards or so... Spark plug out,,, ***No Sparks or youll be on fire.*** doing this...

Take your bick- lighter,,, heat the wet spark plug where the electrode is,,, dont carbon it up with the lighter,,, kind of like the candle thing...

If you have a burning candle flame too close to a odject your heating up,,, it will leave a black soot on the object...

The trick is too hold it at just the right distance too cook the wet/ rich spark plug dry,,,

so its not dripping wet...

If a 2 stroke spark plug gets to wet with the fuel and oil mixture,,, it makes it hard for the spark plug too spark...

If the oil/ fuel mixture impregnate the ceramic porcelain where the electrode is... the spark plug might not make spark at all...

Any ways,,, lets make sure your getting spark and fuel first,,, we can help you out from there...

What kind of 2 stroke oil ***brand*** are you using,,, and what mixture do you have it at...

20:1,,, 32:1,,, 40:1,,, ect...

Like the old guy said...
Not too strong of a oil mixture,,, and deffinaly not too weak of oil mixture...

If a engine has the correct A/F and proper timed timing,,, it should fire up...

Proper A/F and spark makes it happen...

Please keep use up to date...

well as I explained before I do not know a lot of the technical jargon this is my first motor experience other than changing a battery so you kind of lost me a few spots in that whole thing but I think I get the gist of it I am going to try starting it with a choke close to begin with if that does not work then I will weed out some odor and start again see if flooding is the issue and I will wet the end of the spark plug before thank you very much for the help
