2-cycle starts but only stays running by throttling between choke and full.

I suppose this will be the millionth post for rough running 2 cycles, but I can't seem to find a similar situation to mine.

I have a Tecumseh 2 cycle engine that, previously, would start only by adding fuel to the cylinder, then stall. I changed the diaphragm and now it starts without priming but will stall if you don't keep the throttle moving between choke and full. It will stall if you leave it on choke alone and won't stay running unless the throttle is constantly revved at a "sweet spot" just below choke. It is a rolling weed trimmer and continues to run the same way when load is applied (engaging the trimmer head). Any suggestions? This trimmer is a monster and I would really like to save this machine.

Thanks, Marc

Sounds like the carb needs a good cleaning.
