I have replaced the spark plug and I cant get the snow thrower to start, it has tension on the cord and I pull and it makes the right sound it just wont fire. It has a 4.0hp briggs and stratton motor and has very low hours. The actual model number is 536-88140. And yes the oil is full and recently changed and of course it has gas and I've made sure I didn't flood it.

Draining the gas from the tank doesn't drain the float bowl in the carburetor. It still had last year's gas in it. Gas will start to turn to varnish if left sitting 6 to 12 months. You'll probably have to remove the carburetor, disassemble it and clean it out with Gumout carb cleaner or some similar product.
When you get it running and the snow's over and done with, put some Stabil in the gas tank to prevent the gas from converting to varnish and then start it up and run it until that stabilized gas is through the carburetor and into the engine. You can leave it with the treated gas in the tank.
Pull your spark plug out and see if the cord will pull out, if it does than that means your cylinder is full of gas which is a result of ethanol in the gas causing the needle valve to leak causing fuel to siphon from tank to cylinder, pull your carb off and put a carb kit in and you will be blowing snow in no time,if this isnt the problem then enjine may be seized up and its time to replace blower. Good Luck!
Try the spring on the governor. sounds like it's not hooked up, or extremely week. I rebuild and sell these all winter. I've had it happen a few times. Runs really good! but, will ruin the motor running over speed like that. There are adjustments- some have the spring on a long flange of metal so it can be bent backwards to add tension- it doesn't take much! If the motor starts to rev up and down and up and down, add a hair more tension. It there is too much tension it will stall out when you hit heavy snow.
I have a toro 98 cc powerlite snowblower model 38182 it was running fine one day then bog down and died after that i cant get it to start it has a good fire on the plug plug isnt very wet it pops threw carb once in a while help
thank you for the reply. with the belt drive take a ruler and push the belt down you can use your finger as a referance point if you can push it past the half inch mark the belt needs to be tightend you can do that by adjusting the belt tensioner thats done by losening the bolt that holds it in place then moving it so there is no more then half an inch of play in the belt and retightning the bolt. and if the tensioner is at its stops then the belt needs replacement.
Try taking off the fuel bowl and check for debris or ice in it.If there is hardly any fuel in it you may have a plugged or pinched fuel line,try blowing back through it[might get a littl gas in your mouth],turn off the fuel and remove the line at the carb and the tank.If niether of these pick up a new spark plug and try that.
I would check it at the start of every season and clean it. If you note that it seems to be running rich and might have fouled the plug, you can always pull it and check it again. Probably not a bad idea to check it before you put it away for the season. As for replacement, it depends on condition. I would think that you should get two or three season's use out of it before needing to replace it, at least.
