99 Simplicity....am I doing something wrong?

Hello,

I recently bought a 99 simplicity and used it for the first time today in about 4+ inches of snow.

I was really disappointed. It just didn't seem to throw the snow. 15 ft max but usually quite a bit less.

Its a 24inch cut with a 8 horse tecumseh. I replaced the rotten fuel line, the beveled chute drive gears with metal ones, fixed tire, changed oil, and adjusted carb a little bit.

It seems to run fine, and it does run up a fairly high rpm. It never bogged or slowed down just didn't want to throw snow. Auger and impeller didn't seem bent at all and shear pins were fine.

Last year I used a junky yard-man with a 10 or 10.5 tecumseh and 30 inch cut and that thing chucked snow.

I've also used an older cheap 24in craftsman that would put my simplicity tank to shame.

Am I doing something wrong? I noticed the inner chute had no paint and was rusted, not sure if that matters much.

Is impeller belt driven? Could it be slipping? Or is the norm.

check the belts for wear and if they are adjusted properly. otherwise you may have to stick a impeller kit on it. ALOHA to the forms..

Long LIVE THE POWERSHIFT!! MAY IT NEVER RUST IN PEACE!!

also check the impeller bearing for wear. grab it and see if there is a lot of play in it. up and down side to side.

Yes, tighten the belt or replace it. As the belt wears it gets thinner and runs lower in the pulleys. This slows down the impeller speed. If the belt actually slips well that slows the impeller down a lot.

Maybe get a tach to make sure the engine is at 3600 RPM.

The impeller kit is good too. That will help with distance as well as slushy snow.

Sanding and painting the chute is great. The rough surface creates a lot of friction and slows down the snow as well as causes it to stick. The stuck snow causes more to stick and so on.

The last thing you can do is change the pulleys for the impeller. A larger pulley on the engine will spin the impeller faster. (impeller RPM = engine RPM x engine pulley diameter / impeller pulley diameter) Most blowers are around 1000 - 1100 RPM for the impeller, but can be pushed up to around 1300 RPM.

Please direct all snow blower questions to the forums and not to me with PMs.

What was the outside air temp?
If it was 30 to 35 (F) or so, that throwing distance would be totally normal,
because the snow is very heavy, slushy and "wet".

If it was 25 or colder, the throwing distance would probably be double,
and completely acceptable..

"Snow type" as it relates to temperature plays a major role in throwing distance..
"the colder the better"..
for many machines an "impeller kit" will improve the "wet" throwing..

sscotman and shryp you make both very valid points but maybe we have to consider he had only 4" of snow which is dependant on the speed he was going or if slushy then normal plus dealing with a rusty chute?

Snow Removal Apparatus I own:
Ariens ST1530DLE, and good ole arm powered scrapper.
The 15 HP is a new Ducar engine sold
by Princess Auto in Canada.

Thanks for all the replies,

I didn't get a chance to work on it today. Although I did use it pretty hard.

Today it snowed a little more so I was able to test it.

Heres some photos. I left it outside last night, doh.





It seems to working pretty decent now, the temp was warm and the snow was wet but I wasn't moving fast.
I realized that I was asking too much of the thing. Going to keep it as a back up. I bought a Ariens Platinum SHO 30". I really need to throw the snow so it doesn't build up crazy banks. Still not use to the auto steering yet.

install an impeller kit and it will double or even triple the throwing distance
