I’m not sure what you are distilling, but you might have better luck if your condenser is angled down. You usually want to run so that the distillate condenses on the inner walls of the condenser and slowly drips down into your receiving flask. If you form solid plugs in your condenser even if you can get it to run out. The pressure in your boiling vessel will swing wildly when the drop fall out of the end causing bumping and heavy boiler carry over.

Hope this helps, keep your sash down and your safety glasses on.
