Stihl 200t problems running.

[cmguk22]

So I have a 200t that runs perfectly when its horizontal on my workbench, but when I hold it and lower the bar the revs drop slightly, sometime it even stalls. 

 

Grateful if anyone has any experience of this or any ideas what the problem could be.

Split fuel hose that opens up when the av allows it to ?

Fuel filter hooked up and out of position in the fuel tank, perished and split fuel line as per stubby, shyte in the carb gauze strainer shifting around, split inlet manifold with the split opening up when the handle is gripped.....what happens if you hold the saw down horizontally and then pull on the handle?
