How To Get a ARIENS Snow Thrower To Run Stronger /Faster

I got a new Ariens at Homedepot two years ago. And after using it 3 or 4 times I was unhappy with the slow or low RPMs . So I took it to the dealer while still under warranty. And showed them the problem. They told me that because of the EPA there are no carborator adjustments they can make for me .
So this winter came and I had to do something because it was having to much of a hard time with the heavy wet snow . So after checking spark plug and valve gaps , pulleys and belts . I had a brain storm for this SIMPLE FIX .

All I had to do was file to right side of the throttle slot open a little more , a good 1/8 " with a small round file . To get the throttle arm / lever to travel a little more to the right which gave the motor more gas . This gave the snow thrower about 100 more RPMs

Even though this is a unauthorized repair it DID WORK GREAT !
So what is the throttle slot , it's the square hole that the throttle lever moves in from slow / turtle to fast/ rabbit the hole job should take no more then 3 mins to do. I hope someone make this a sticky because it should work with all snow throwers !

I think the dealer blew you off.

It should be a simple governor adjustment, not a carburetor adjustment.

My fix didn't need to be for the governor or the carborator . All I did was gave the carb more gas by increasing the spand of the throttle.

The governor works by balancing spring tension with the flyweight in the crankcase.

Increase the spring tension and the throttle will open further for given movement of the throttle. No need to increase the span.

On many small engines the spring tension is adjustable by bending a tab.

I don't quite understand what your saying. I though the governor keep the crank from going over speed.

Do you have a tach to have seen before and after?

I have to agree with this statement. They should have put a tach on it and verified the high speed RPM's. And they can adjust it, just not the mixture.
