Why won't my two stroke run? Answered

I have a two stroke weed eater engine (actually from a tiller but it's the exact same) and I am having trouble getting it to run. I have the carb screw tightened all the way so the carb is opened up as much as it can be but when I start it, it coughs like it wants to die then it dies. If I squeeze the throttle a little it will continue running or if I squeeze it all the way it will still run. It just won't run if I let it sit.

Also, I am intending to use it to put on a bike and it has a clutch but it doesn't really work that well. It will engage without even squeezing the throttle. Any idea of where I can get a small geared clutch that will fit it? Thanks.

Most manufactures will have a user manual
that also describes how to adjust the carb.
So just do a search for the tiller model.
If your carb happens to be a "Zama " brand,
You can go to the Zama site to get carb adjust info too.

If the needle is screwed in then you have it closed. It's starving on idle. Open it up some and it should idle.
