Jiffy auger problems!!!!

[littlemikey]

I have a jiffy 3 hp stx 10" auger and it doesnt idle at all. when your cutting a hole it runs ok as long as you keep on the throttle, but if you let off and then try to pull on the throttle again it cuts out and dies unless you can prime it fast enough. also if you let off on the throttle it will not idle at all. I bought auger last winter and have had the problem since it was new. was wondering if anyone else is having problems?? also i heard it might have something to do with the idle and high speed screw on carb, but i have no idea which one to turn or how much to adjust it. Any help would be greatly appreciated.

There should be a brass screw that sticks out, with a spring over the treads. I've never had a Jiffy but that is the case with almost everything with a carb. Test 1/4 turn at a time until it gets to where you want it. If you go the wrong way you'll know.
