Good afternoon everyone, new here. I have a Stihl FS55 Weed Eater that last season I lost the idle screw on it so I decided to just put a new Zama carb on it. So this year I put the new Zama pre-adjusted carb on it, replaced the fuel filter, air filter and spark plug. I also replaced the fuel in it with the premixed Stihl gas. i can get it to run but it is very touchy. If I have the choke off it will idle for a bit but as soon as I go to give it throttle it sounds like i bogs down and turns off. The only way I have been able to get it to run is on half choke, a little closer to full and the throttle is still very touchy. If I find the sweet spot it is fine but if I still give i to much it starts to bog down, I go back to idle and then find the special spot again. I have already gone through the spark arrestor and it is clean. Any ideas on where to start? Thank you!

I will try swapping the gas lines tomorrow and seeing what happens. Sucking air from where the gasket it? I can check that too but I didn't see any problems with that when I checked it before.
