    When running does it surge or pulsate any before you put it under a load?

Sounds like you broke the belt. The auger housing should be held on by a few bolts between the auger and the engine. Remove the bolts and it should come apart into two pieces. You will most likely find a broken belt there.

Many small engine problems such as you described are fuel related. In today's world, most of our gasolines are blended with ethanol and thus gasoline shelf life has been reduced to 4-6 months. It is important that after each season's use you be certain to run the snowblower until all gasoline in the tank and carburetor have been used - effectively running the snowblower out of gas. If you did't do that last season the "old" gasoline in the carburetor has began to gum up and will not let the carburetor mix fuel and air properly. The solution will be to remove, disassemble and clean the carburetor. It is likely the gas tank will also need to be drained, removed, and cleaned. If you are unable to do this you will need to take to a qualified small engine mechanic in your area.

Lastly and, very importantly, make certain when you are ready to use your repaired snowblower that you use FRESH gasoline. And, remember the first part of this discussion at the end of the season.

I have a ******* troy bilt snowblower it won't ******* stay ******* started can anyone ******* not refer me to ******* different ******* brands and leafblowers and other ******* things other than


The diaphragm in the Carburetor is probably bad. If you are mechanical it is not that hard of a fix. Of course this is assuming that you have cleaned out all the old gas and replaced it with 100% real gas. NO ETHANOL. I also keep gas treatment in all of my tanks and spare gas cans. Varnish from old gas makes small engines like snow blowers that are only used seasonally a Bi*** to start and keep running.

Order or go out to your lawn center and buy a new diaphragm, I bet it fixes it.

I have spark but it will not start


Drain the gas and carburetor and refill with fresh. Clean the air filter if it is dirty. See if this helps.

MTD Snowblower starts good but runs very rough


Carb adjustment. There is usually a HIGH and LOW fuel mixture adjustment on the carb. Sounds like the LOW needs to be adjusted. Do a search on the Internet for a service manual for your particular model/make. Simple job IF you have the manual there for guidance.
Good Luck

I assume this is on a snowblower?

Be sure you have fresh fuel.

You can also remove the bowl on the carb and spray carb cleaner in any orfice you see.

Always store a snowblower with fuel stabilizer in it. Otherwise it the fuel can "varnish" the inside of the carb and cause problem.

If it still doesn't start check compression.
