Snow thrower

I'm having a difficult time trying to start my Ariens snow thrower.

after following the Ariens starting procedure,i have to pump the primer 7-8 times before it will start from a new cold start. After I get it going it runs fine ,and it starts fine, thereafter ,next cold startup is where my problem is.
choke full closed, middle throttle setting,prime. I've tried half choke, full choke.

Any suggestions are appreciated

Thanks

Have you tried starting it at Full Throttle ?

Sometimes it just takes experimenting to find how that engine likes to be started. I normally start with priming 2 or 3 pumps after I feel the bulb get hard (full of fuel) and have the throttle cracked a bit off of idle and have the choke on. If it sputters and tries to fire I'll open the choke and try starting again.

I'm Vermont on this one.
I start all my gas powered equipment wide open except my Stihl blowers because that would shut off the choke.
Every gas powered tool is different even if there the same model.
I have two exact same model leaf blowers, one I have to start without priming or it floods. the other one takes three pumps or it's not going to start.
If it was mine I'd try only pumping the bulb 3 or 4 times and have the choke and throttle full on.

Every engine that I have has its own personality, and likes to be treated as an individual; but I just read the instructions for the Tecumseh Engine that powers my 2007 Snowblower . . . . something that I don't recall doing since it was new !

The Instructions, which I've been following religiously (or habitually) for over 10 years, say to move Speed Control (that seems to mean Throttle) all the way to FAST (which would indicate Full) and to position the Choke at FULL in preparation for Starting.

Then, upon being started (and paraphrasing Tecumseh's Instructions) I immediately begin reducing the Engine Speed about 25% or more and I slowly set the Choke to about or less while I let the engine warm up without any missing for a minute or so . . . . and when warmed up, I eliminate the Choke altogether and return the Speed (Throttle) to FULL while I put the machine to work.

Choking any engine should be considered ONLY as an aide in getting it started; not as a setting while it's being used.

I recognize that Tecumseh is out of business; but their instructions still work for me.

This is exactly how my Arien Snowthrower is started. This is typical of most all gas powered engines.

I tried to start the machine as many of you suggested. It started eventually after priming
10 times ????. Warm start is no problem

It could be that your tubing from the Primer to the Fuel Bowl is deteriorated ?

Myself, I've been fiddling with my Primer this December as the Tube has chosen to fall off the back of the Primer Bulb !

Rather than take everything apart and properly re-attach the Tubing to the Primer Bulb, I have INSTEAD been getting everything ready (110 Plugged into Starter, Throttle set on FuLL/Fast, and Choke Closed/FULL) and then I get down on one knee and I blow a couple of lungs full of air into that Tube, and immediately engage the Starter . . . . and it's been working for me.

Why do today what you can put off until tomorrow ?

I'm really just waiting for a day when it's warm enough for me to handle s few tools outside (and I think of this task) !

That primer is an air pump that pressurizes the float bowl and forces gas up into the carb throat. Take the tube off at the carb and check it for air coming from the bulb. If it is, hook the tube back to the carb and take it off at the primer bulb. Blow in the line while tipping the open carb end downward. You should get a fair amount of gas out the open end of the carburetor.

If not, check the carb bowl gasket with some liquid soap for air leakage.

GOOD MORNING ALL,
I finally got the beast running last night.

I set the choke to full opening, speed lever to fast, pumped the primer 3-4 times and tried starting. Engine STARTED then stalled. I pumped the primer a couple more times and it started and ran.

3 degrees here this morn I'll try later

Thanks to you all for your help and patience

That's the normal starting procedure. Mine is a Deluxe 28 SHO. Full throttle, mid or full choke, and half a dozen pumps on the primer bulb.
