No power and only runs with the choke on

The Ariens in my Sig does not have much power and will only run at 3/4 + choke. put the choke at 1/2 and it dies. I did not really use it this winter because of this reason. Any thoughts?



Ariens ST724, 1983? Model #924048, Tecumseh 7 HP, H70-130210H, No Electric start. Purchased 11/15/2013 from OO for $150.

Thanks for helping me out!!!

So I unscrewed the screw on the bottom of the carb bowl and it seems to have worked. I adjusted it so that it runs with the choke off. Do you think I am all set or could I need more adjustments and or maybe a new Carb? Jacks has a new carb for $83 and Amazon has one for $20. thanks again.

Leave it, it's Fine. Now You know how to adjust it. Adjust the Screw on the side if it cycles.

it might be cycling just a little. If I am looking at the picture of the carb is it the screw on the left near the muffler that I would adjust? Thanks Again!

Run some Seafoam through the gas to clean the carb...and adjust as necessary....fresh gas is your friend.....

The carb is dirty, and I was going to say it needs to be cleaned. But if Jackmels say it's OK to adjust it and leave it, then do what he says

It's been a long time since I've had a blower with an adjustable carb, sadly (sigh, EPA regulations). Mine would simply need to be cleaned if they did this. But if you can get it running OK by adjusting the carb, then that's great!

Using fuel stabilizer will help avoid the problem getting worse (it could have helped avoid this in the first place, but you can at least make a change going forward). I use it all the time (cheap insurance), but at least use it in the gas that's used before the end of the season.

Ebay carbs are adjustable, and are inexpensive, I've used a few with good results

Yellow Circle is the screw if it cycles. It is hunting for the correct mixture. Sometimes you need to adjust them both (screw on bottom as well) to get harmony.

you beat me to it. I was gonna ask Woody when was the last time it was ran and if it was old gas.

This topic should be a sticky since it comes up so much.

Just make sure you get the adjustable ebay carb. They sell a lot of non-adjustable carbs on there too.
