Ice auger carb adjustments?

11 posts in this topic

I know I'm going to sound stupid on this one....

Yesterday, I fired up my dad's ice auger for the first time this year. It took a long time to get it past the choking stage. Eventually, I was able to run it, albeit at half choke. I took it out last night and no problems.

This morning, I could only get it to start briefly, but not to run longer than 30 seconds. Any time I turn off the choke altogether, it dies. I took it home, messed with it, and can only get it to start if I pull out the air filter and splash a little fuel in that way. I can get it to run briefly at half choke, but it always dies.

I know my dad has messed with the jet and idle screws to some degree. Would it help if I reset these and start over or do I likely have a bigger problem? If so, how do I do this? I do not have an owners manual....is it like a chainsaw where you just screw them down tight and back off 1 full turn?

I want to go fishing tonight but all the small engine places are closed....and it's getting tough to move around much with a hand auger.

Be sure to post what the make and model is. I had something similiar, and received timely helpful assistance on here.

My bad...it's a Tecumsah Magnum 49cc III plus. I just went out and same thing...I have to pull out the filter and dump gas in that way. Runs for a moment and dies.

Have had that same auger since late 80's. Can't even imagine how many holes it's drilled in it's day... Anyway, had the same issue this week with mine. Usually do right away when I first start'er up for the season. 2 things to do (if you haven't). First, bring it inside to warm up..get some carb cleaner...pull the sides off (Diaphram)and the air filter...spray'em down good. Second, make sure you have new gas mixed and put Seafoam in it. May never have another problem... \:\)

Well....I took your advice, removed the diaphragm and air filter, dumped the old gas, cleaned the carb up. I used Sea Foam Deep Clean. The auger fired up, ran well for about a minute....even with the choke off for the first time. I shut it off, put the air filter port back on, fired it up again and it quickly revved up and seized! Now I can't do anything! What the heck happened? Could that be the jet misadjusted? Is there anything I can do now????? Crap.

Try this:

Turn the low-speed adjustment screw clockwise until it lightly seats. then turn screw counterclockwise 1 1/8 turn. then turn the high speed adjustment screw clockwise until it lightly seats. Then turn screw counterclockwise 5/8 to 3/4 turn. The low-speed screw should be on the left and the high speed screw is on the right and the high speed adjustment screw is larger in diameter than the low-speed adjustment screw.

Been having troubles fine tuning my auger also. runs great and wide open wiht half choke. no choke it starts drilling the first 3-4 inches and then bogs down a lil. sucks when i drill about 20-30- holes in a spot when it bogs down under load. i have the jiffy stealth stx 3 hp. any ideas or what screw to adjust

Here is a link that should give you your advice. Mine runs like a champ now....and cuts fast as heck.

      Most of our fish came on minnows under bobbers. I spooked countless fish with even subtle jigging.

      Hey, Here a quick update on actual ice thickness or snow cover on trout. 14 inchs of ice pressure ridge out there. if you are  on a snowmobile if traveling fast on it watch for it. Truck or car i do not recommend on trout with pressure ridge. And yes i have been on the whitefish chain this year in truck. just not on trout. just my 2 cents

      Thanks for the info everyone. And Borch that is good to know too.  I try to spend 2-3 hours looking on cedar each trip, but It's a lot of water to break down , and having only been out hardwater cattin 6 times so far I still have a lot to learn.  Generally I spend a lot of my 3 hours losing confidence and then wind up at the meth hole to catch a few .  Putting in the work is what makes it so fun once it all comes together though!
