Jiffy 3hp Stealth Auger Issue

[NAG]

I have a 3hp Jiffy Stealth auger with a Tecumseh motor. It is about 4 years old. I am having issues with it stalling out at high speed. It idles fine and will run at high speed for about 5-10 seconds and then it wants to stall out. Once it stalls it starts right back up and idles fine. I ran it in the summer and it ran fine until a few days ago. I pulled the carb adjustment screws and sprayed them with carb cleaner. Reinstalled the screws to factory settings. It is still doing the same thing. Any ideas?

put new gas in it.. clean the air filter check the muffler isn't plugged...

I had a million probs getting my 3HP to run right.. fresh gas always works.. and I also mix it 75 to 1 with synthetic oil.

I have the same auger... It does the same thing if I dont let it warmup for about3-5 minutes.. The are cold blooded...

Today I let it warm up for 10-15 minutes and still experience the same issue. I will check the muffler and air filter. I am using premium gas with Jiffy oil mixed 40:1.

Mine is over 20 years old, JIFFY 30 10". Good gas and some adjusting is all it has ever needed. Looking for a 8" auger to change sizes when perching. Seen a lot of other brands go to the heap and the JIFFY always can be fixed up for little to just a good cleaning. Brother also has same JIFFY that is older.

Gas can be the decideing factor in the running. One step farther is run sea foam in the gas. It can only make things better.

I will try new gas. I also checked my model and it does not have an air filter. The muffler also looks good.

When it dies out hit the primer. I have to do that with mine until it warms up on really cold days.

Have you checked to see if you have opened the tank vent on the fuel cap? If you have, open the high speed adjustment about one quarter turn counter clockwise. This will allow more fuel in to the fuel well in the carb body.

Also check the fuel tank on the inside where the fuel outlet is located. I have seen any number of items in the fuel tank that will gravitate to the fuel outlet, and cover the hole for the fuel. As soon as the engine dies, the obstruction will come free, and allow the engine to run for another short period of time.

I opened the high side about another quarter of a turn and it seems to run a little better. Went out on the ice and drilled a few holes and can still tell it is not running at full power. Right now the carb is set at 1 1/8 turns out on the Low side and about 1 turn out on the High side. I think I might jus thave to mess with it some more in this cold weather.

I heard theres a place in big lake that will solve all your problems.

I hope this might help you get it running right.

ADJUSTING TECUMSEH 3 HP CARBURETOR

pop the red caps off.

Close both jets GENTLY

Open the Low speed 1/4 turn

Open High speed jet 1 1/4 turn

Start engine.

Adjust low speed until idling smoothly.

Open her up wide open.

Adjust High speed until engine transitions smoothly from idle to high speed without bogging.

Shut engine off. Let it cool.

Once engine is cold. Fire it up and let it idle for 30 secs. Open it up wide open again. Adjust if necassary.

The trick with the Jiffy's is to tune them during cold (ice fishing) weather.

Low speed screw,the one on the left.

High speed on the right.

I finally think I have it dialed in correctly. I am heading to the lake tonight to try it out. I switch to Amsoil Saber and mixed it 80:1. To get it running right I have the Low screw set to 1 turn out and the High screw turned to 1 1/4 turns out. Seems to run great with no load on it.

Let us know how it runs on the ice for you if ya have time.

[westrush]

I have the same auger And I played with it for about a hour making adjustments And got it to work great after that Benn fine ever since

[NAG]

Went out last night and drilled about 15 holes to teest it out. I ran perfect at high speed, but after each hole it wanted to kill. I think my low side might be off a little bit as it always started back up. I did notice when it does idle it sometimes idles up and down on it own and if you tilt it a little it kills. Is that normal or should it stay running when you carry it with a little tilt?

[cold one sd]

If I didn't carry my 3 hp pretty much verticle it would kill between holes. I can carry my 2 hp horizontaly and it will keep running. I don't believe I have seen a 3 hp that would stay running if you layed it down.

[MuskieJunkie]

My 3 hp stays running muffler up but not the other way.

Thanks cold one for the tuning tips.

Spark plug up (or muffler / same side) per Jiffy recommendations. They will not run with the carb up.
