Will not throw snow - Garden

Do you rev it up when you use it? they are made to rev up. Are the paddles that throws snow worn? Even if the skid plate is worn but the snow is getting to the paddles it should throw snow. In saying that no snow blower will throw good if you do not have much snow. The more the better it should throw. They won't work well if there is under 3 to 4 inches. and really throw well.

Did it throw snow better in the past? Or is this Blower new to you and you expect a better Throw?

I had to replace my carb and while I was in there I increased the govenor speed. The extra rpms throws the snow a little better.

I take it that you have a 2-stage snow blower, that is is has the auger blades and then the 2-stage impeller. The impeller blade is damaged <<OR>> the motor is to small to through the snow far. If you have a 5-horse engine and throwing heavy snow, the snow may not go as far as the light fluffy stuff.
A single stage snow thrower is not designed to throw snow far, just move it over a bit.

blower might still work but gear case that runs auger is shot or you sheared the shear pins in auger

It should slow down some as it is under a load. As long as it throws the snow far enough no problem. If not the speed governor may need adjusting. Make sure you have fresh fuel.

belts are streched and slipping

It's possible your auger may be worn, and it is not moving / propelling enough snow to make up the difference to blow the snow at the angled setting. It may throw the snow forward better due to less resistance, rather than the snow having to propel around an angle / curve. Just a thought for now.

I will assume you are referring to the 2 stages in the front of the machine. The spiral auger rakes are the first stage, they are designed to collect the snow and feed it to the impeller. The impeller is the 2nd stage and is to throw the snow up the chute. The lower rakes in the front do nopt throw snow only collect it.
