Possible problems
Belt slipping ( too loose or worn out )
Snow too wet and plugs up.
Motor not powerful enough could be running too slow
Could be the gas screw on the carb set too rich and floods or too lean.
Could be trying to blow too much snow at a time.
Depending on the machines age could be just wore out

Making your​ snow blower throw further

The other reason could be that the auger drive belt is worn, which can lead to the same result. In any case, a snow blower not throwing well is usually a symptom of a belt that doesn`t grip the auger drive pulley effectively.

A dirty carburetor is the most common cause of a stalling snowblower engine when the auger is engaged. Cleaning the carburetor and fresh gas will fix the stalling.
The higher the impeller rpm, the farther the snow gets tossed. There are impeller kits that can be added to your snowblower. Keep in mind, however, that any modifications to the machine might impact its warrantee.
Toro snow blowers have a wear mark on the paddles (it is a small pinhole). If it`s worn past that mark, it`s time to replace the paddles. The gap on the paddles and the auger housing should be very tight. If the gap is not tight, the snow blower won`t pick up as much snow and throw it as far.
Turn off the snowblower engine and leave it to cool. Remove the carburetor bowl, float bowl and flathead. Spray and clean the dirty carburetor with a carburetor cleaner, removing debris with a cloth. Let it sit to remove impurities.
Big Jobs Call for a Snowblower

This Old House recommends spraying the exit chute with a silicone (like WD-40® Specialist® Water Resistant Silicone Lubricant) to keep snow from sticking.

Engine RPM bog down occurs as the engine is loaded beyond its torque-producing capabilities. This occurs when engine RPMs are allowed to decay below the design specification. Bog down can occur during ground start, taxi, and the landing roll.
What is Bogging? When a dirt bike bogs, it simply means it`s not getting enough fuel and the engine sputters or stalls at full throttle. There are two common types of bogging: lean bog and rich bog, distinguishable by how the bike sounds when you throttle.
If your snow blower is cold, you`ll want to pull out or turn on the choke while you`re starting it. This closes off the air supply to your carburetor, which makes for a much richer fuel mixture. If your snow blower is stored in a heated garage and is warm enough, you should not use the choke.
Two-stage snow blowers do well with up to 2 feet of moderate to heavy snow. Three-stage snow blowers are best for heavy snow, ice and slush up to 2 feet deep.
A snowblower that won`t move or moves very slowly may have a worn or broken friction disk. Friction disks can wear down over time and will stop engaging properly. Inspect the disk and if it has any signs of damage then it may need to be replaced.
How far should a snow thrower throw snow? Under nominal testing conditions, most multiple-stage* snow throwers in good working order should throw snow a distance of approximately 15-20 feet.
For removal of snow in normal conditions, such as a paved driveway or side walk, place skid plates in the highest position (lowest scraper clearance) to give a 1/8″ clearance between the scraper bar and the ground.
Why does the engine speed increase and decrease slightly every few seconds when it is at idle? It is normal for a snow thrower engine to run in this manner. The engines on snow throwers are set to run with a slightly rich fuel mixture.

My snowblower does not seem to run at full speed. Barely throws snow recently. Any adjustments I can make?
ANSWER : There is a spring attached to the throttle linkage. At the other end is an arm that the spring attaches to. Bend the arm so that the spring is tighter and it will throttle up higher under a load. Don’t go too far or you will take a chance of blowing the engine. Best to use a rpm tester and set it to factory specs.

The engine starts but won’t actually throw snow the wheel that turns to throw snow is not turning
ANSWER : There is probably a shear pin or bolt that has broken, providing all other belts and accessories are intact. Should be very simple to take the bolt out of the wheel where it attaches to the shaft. Just take it to a hardware store or an outdoor store that sells snowblowers.
