I changed out the carb last year and It was running pretty well. It would start realiably and idel well. I went to use it to spray some weeds and it was at low speed idleing a lot and it was hot out and it died. Started back up like 20 minutes later and then died again. I let it sit for a couple weeks occasionally trying to turn it over. No success. Tonight I sprayed some starter fluid in it and she came to life! Ran for about five minutes and then started to idle rough and eventually died. I sprayed some more starter fluid, got her running and every time she was about to die id give it some throttle and it would sound like it was choking or sputtering from the air box. Then it would die. Relatively new China carb about a year ago. I’m at a loss. Any help would be appreciated.
