Back firing could be an ignition, or valve timing issue, also check the function of the anti fire solenoid on the bottom of the carb float bowl ( you should hear this click as the ignition is switched on) you can also remove it and watch the centre pin retract when the ignition unit is switched on, next thing to check is that the flywheel key has not sheared, this will involve removing the flywheel, failing this remove the rocker box cover and make sure both valves are moving freely as the engine cranks, it could be a stuck valve.

* Handheld units are the most popular. Available in gas- or electric-powered versions, they're portable and convenient, yet powerful. These models can get heavy while using. Larger models can also vibrate a bit at full throttle. Consider the weight and balance of the unit when shopping. * Backpack leaf blowers are gas-powered. The blower fits in a harness that's worn on the operator's back. The hose reaches to the front where the user operates the throttle and blow or vacuum tube. Backpack blowers are normally used in larger areas. * Walk Behind leaf blowers cover the most acreage. Mounted on wheels, these gas-powered machines are normally the tool of choice for commercial users, but for regular homeowners, they can make short work of a home lawn. Vacuum units use a hose for picking up debris.

You may need a new one. If that doesn't work you may have a bent pulley that's cause it to jump off or the barrings in one of your pulleys may be bad which would cause the pulley to wobble therefore throwing the belt off.

It may only need unplugged to reset rather then taking inside.

Likely it's a thermal switch. Try running with out moving snow and see how long it runs.

it needs fuel.

Typical snow blower shifts by moving a drive wheel on a hexoganal shaped shaft. Likely the wheel has rusted to the shaft from insufficient maintenance.

Remove the rear/bottom cover plate to access the transmission (usually 4 bolts). Lubricate shaft/wheel with penetrating oil and work free.

Avoid getting oil on the drive wheel and disc or thoroughly clean the disc and wheel with a liberal application of alchohol until wiping with a rag comes clean.

Lubricate any drive chains as well.

Hi Jacquelin- I found this link. https://www.manualslib.com/manual/772531/Toro-38588.html?page=16#manual On page 15-16, it talks about the "Replacing the Drive Belt". This might be the problem. Hope this helps.

Hi Bonnie- I found this youtube video. https://espanol.video.search.yahoo.com/search/video?fr=yfp-t&p=toro+zero+turn+mower+steering+handles+loose+and+hit+how+adjust#id=1&vid=22a3597924a9902209fcda071ec4a144&action=click Hope this helps.

Carburetor float is stuck or debris in needle valve.

If you didnt treat fuel before storage last season then likely the carburetor is fouled. Try adding a fuel treatment e.g. Seafoam, but likely ithe carb will need a thorough cleaning or replacement.

Let warm up if still does need new spark plug

Try a short burst of starter fluid into the carburetor and promptly pull starter. If it runs for a couple seconds and quits then the carburetor is not delivering fuel.

If it doesnt run on starter fluid then either flooded, insufficient spark, or poor compression / crankcase leak.

replace the ignition coil

I have had the same issue with Toro. Finally took it to a local wizard. AFter about 5 minutes if him trying he suggested it would make a great boat anchor. Once Toro goes out of factory specs, that's just about it. A few lucky folks I know with Toro products either accidentally stumble on the just-right combinations or off to the lake they go.

Check and see if there is a shear or safety pin in one of the drive pulleys that has broken.See if there is a pulley that turns by hand when this happens. Could be one has broken but grabs for a little bit. Also check the drive belt and see if it is slipping Check all the drive areas . BE SAFE BY TAKING THE KEY OUT AND TRYING BY HAND>

Ditto... flywheel key has sheared.

what belt did you change? i assume the drive belt. if it is not exactly the right size it wont work. if it is not routed correctly it wont work. it may have slipped off of a pulley.
