I have a Strikemaster Magnum 49cc III Plus Ice Auger, and I need some help with the adjustment screws on the carb. It starts fine with a full choke, and no throttle, and then at half choke I have to give it lots of gas just to keep it from dieing. With no choke at all it will not stay on. It has a rebuilt carb on it, new spark plug, and new gas mix. I've searched for the factory settings on these adjustment screws but I can't seem to find the info anywhere. I'll take a picture at lunch so hopefully you guys will have a better idea of what I am talking about. (and hopefully can help me!!!)

**Added Picture***
I understand each screw has to be changed in small intervals, but does anyone know what each individual screw does? I currently have the smaller screw on the right turned out about 1 and 1/4 turns, and the larger screw on the left is turned out about 5/8 of a turn. It starts fine in full choke, and does ok at half choke for a few seconds and then dies out.

here is what I did with mine I turned the fuel mixture screw in till it just barely stopped than when it stopped I went a full turn and a half out with it got it to run than just adjusted it till it ran smooth. you go on way it will die get in the middle it should run fine if you go too far it will die too find that happy medium

I hope that explains it

I have this exact same auger and asked a question somewhat similiar to this. It may be on page 3 or 4 but if you need more help go there.

I did the some thing as Big Fish Hunter. I turned it all the way in, and then turned it out about 1/4 to 1/2 turn at a time until I found a happy medium.
Mine would bog out or die after a few inches of drilling.
I was able to get it running good again while drilling, but now it's starting very rough and dies much like yours has been if I dont keep the throttle full on it.

If you work at it for 10 - 15 minutes you should be able to get a setting that works. I'm in the same boat you are, so I know how badly you want to get it running good again!

The jet should start at 1 1/4 turn. then adjust from there,very little at a time.the passage ways in it are small so you may have to take a part again spray carb cleaner in it and blow out with air.You might try some see-foam. Good Luck,Wes Ellis

So I should leave the screw on the left as is? and only adjust the one on the right in small increments?

Assuming the carb was thoroughly cleaned, fuel level set, new diaphragms/kit installed, clean filter/screen in the tank, good connections to fuel line your next step is to adjust the carb.

Since you can't keep it running without choke then richen the mixture by turning out the mixture screw. Do so with very small adjustments till the auger idles on its own with no choke and not having to give it gas. Get to the point of highest idle then back out the mixture screw till the engine just starts to slow.

Now get it on the ice and get it under load. If it cuts good under load and idles good leave it there. If it bogs under load you'll need to determine if the mixture is too rich or not rich enough. Do so very small adjustments. Get it to where it'll run good under load. Now your idle may have changed. Before doing anything with the mixture try turning up the idle speed stop screw.
As you can see it takes some tweaking. If the carb isn't clean, fuel level improper, or warn diaphragms you won't get it to run correctly under both conditions of idle and under load.

The big screw Left,it the idle screw The little one is the mixter. Chanses are the little one needs to be opened a little.But Serface Tension has a good point carb cleaned and fuel level set ,diaphragms installed properly. Wes Ellis P.S. I I worked ice augers for 20 pluss years.

Thanks for the help guys. I'll have some time this evening to work on it and I'll let you know how it goes.

Well I had a chance to tweak it last night, and I still can't seem to get it right. At full choke it idles just fine and will stay running, but as soon as I go to half choke, it floods and dies. I assume this means I need to tighten the smaller screw on the right in small increments because the mixture is too lean, but as I turn this screw clockwise, it only results in the engine not starting at all, even in full choke.
