Snowblower will not start. replaced plug and gas. seems to have no spark
1st off check to see if spark is present. If not, try to disconnect the wires behind where the key is. Check spark again..if now u have spark its a key issue..if not still...get to the coil and disconnect the black ground wire and check spark again. Nooow if no spark youe coil is bad..coils rarely fail in my exp but does happen.
Also..what is giving u the impression it has no spark? Before you try anything else get a spray can of either (starting fluid) and spray (usually in an akward spot or angle to spray) it into the carburetor directly (usually right behind choke knob) & then immediately try to start it then. If it starts for even a half a second your spark is fine and most likely your carburetor jets are clogged and carb needs a cleaning. If ur unsure or not comfortable messing w carb call a pro to do it..it will save time and aggravation.

Unplug the switch to make sure it isnt just stuck in off position *(internally stuck while the switch will still move) If it starts you can unstick the switch with some WD and a couple back and forths with the key.
If you still have no spark you are gonna need a new coil.

There may be a cracked fuel line, cracked primer bulb, loose carburator, dirt/trash in the carb....it sounds like a fuel supply problem. Hard to tell with out hands on.
SOURCE: Troy Bilt lawn mower used months 2009 will not
stale gas in carburator...take the screw out of the bottom of the carb and let the gas run out...
SOURCE: Its starts but will cut off
The problem you are having is due to dirt and gunk in the carbeurator. Spray a carbeurator cleaner into the air chamber [remove the air filter] and run it a couple of times then let it sit for two hours while the carbeurator cleaner does its job of dissolving any debris. Then start it up. IF this does it, great, if not repeat the cleaning technique.
If all of this doesn't do it, then the carbeurator will have to be removed and either replaced or rebuilt.
SOURCE: Hello, I have a Troy Bilt 2410 SnowBlower that
If memory serves me your unit is a 4-stroke and the motor is very well hidden by covers. There probably is not a fuel shut off valve on that unit from the factory, and there is no drain plug on the tank. To drain the tank, pinch the fuel line off between the tank and carb with some kind of locking pliers/ vice grips, then remove the fuel ilne from the carb and place that end of the line in a container and remove the pliers to let the fuel flow. Also, spray a prime directly into the throat of the carb with the choke open. Snow throwers do not have air filters since the only thing they would catch is water ( theoretically).
You should be able to spray the prime to diagnose without too much hassle but to perform any service on the unit you will have to remove all covers and gaurds. Take your time the first time and its not as bad as it looks, after the first time its a breeeze. Some units have a little 90 degree extension coming off the muffler that prevents the removal of one of the covers, with the right sized 1/4 drive socket on an extension you can reach up and loosen the pinch bolt and remove the extension which makes the job a whole lot easier.
Good luck, hope that helped

Take the belt cover off that covers the drive pulley on the engine. You should only have to loosen two bolts. Inspect the belt to see what it looks like. I am not sure if it drives a gear box or if it turns a friction wheel that drives the wheels. If the belt looks good check for shear bolts that might have sheared off and replace them.
