Bike has not been cranked since 1 Nov. 2 gal. of fresh gas with Sea Foam was added to old gas. At full choke, engine will run for a moment and stop. Will not run at all at no choke.

Try running sea foam through ur system take the gas hose off the tank make a funnel system to that hose fill it with straight sea foam crank the bike untill it sucks at least 1 cup full let it sit for 24 hrs then try to start the bike with gas by adding through the funnel still no luck check spark plug for spark if no spark check sensors a wire could have croded and not making good connection also check your fuse box changing fuel pump could have blowen a fuse

yes get a rag wipe off all the fuel . blow dry all inculding the muffler and spark plug make sure your getting spark if you are spray a small shot in the spark plug hole of starting fluid tighten plug if it fires drain fuel tank remove intank filter put in fresh fuel i get some Sea Foam you can get it a walmart or autozone meijers it made for 2 cyle and 4 cyle engines pour sone about 1/4 cup in the emptyas tank try to prime and see if starts if so put in 1/2 cup of sea faom in 1 gal of new fuel and oil get a new gas tank filter there about $5 check wlamart replace when brush cutter gets running find a way to secure it remove the blade or disengage it and make it run maybe almost full choke then less and less but after it runing take it out and run it good and make it work . ( I winterize my lawn equipt with 5gals of 89 octane full i can of 104 octane booster and 2 cups of charcoal lighter fluid ( it kenosee and the fuel would break down or put 1/4 cup in a empty mower start it for 1 minute and leave it you put in fresh gas next summer it has the charcoal or sea foam as a carb cleaner for the season . i put sea foam or lighter fliud in my fuel all yr as ethonel breaks down in 25days

Sea Foam is NOT a gas Stabilizer. Your carburetor jet needs to be cleaned.
MAny Carbs are set up tis way, not sure about your CC snowblower. The jet in the Carb is gummed up. Take that 1/2" bolt off the bottom of the Bowl..That IS the Jet. Many times the Bowl will just hold in place with the Bolt out.. make sure the three holes are clear. 2 are close to the head of this bolt and you should have a 3rd real small hole where the threads end. Screw it back in...see what happens

Clean your fuel system with seafoam for starters...

Sea Foam Motor Treatment

I used to have that same exact bike when I was a kid but I can't remember how many carbs it had??

There is something clogged in the carburetor. You will need to completely clean it or replace the carburetor.

How much gas is in the tank? Is the gas old? If you only have a few gallons in the tank i would advise you to put 5 gals of fresh gas and a bottle of sea foam gas addititve.. if you gas is old it starts to turn to varnish and gets sticky, it smells really bad too.Go to auto zone or wal mart to get the sea foam and add it to a five gallon gas can then add your fresh gas into you car tank..You can also get the sea foam in a spraycan form that you can spray directly into your air intake..Can you hear if the fuel pump is running? Take your gas cap off and put your ear up to the filler tube to see if you can hear you fuel pump working, it sounds like a high pitch whinning sound..Have someone turn the key on while you listen for it..

Has the bike been in storage for awhile for winter? If so was fuel stabilzer used. If not the gas is probably bad. Add 2 ounces of sea foam for every gallon of gas and introduce as much freah fuel as you can to the tank. Take it out and replace every gallon burned with a fresh gallon with 2 ounces of sea foam until the old gas has run through. You may get a lite blue cloud on start up but this is normal with the sea foam, its cleaning out the junk in the fuel system and engine. Hope this helps.

How old is the gas? Did you use fuel stabilizer? If not then add fresh fuel to tank as you use it and see if this clears your probelm. Also I would add 2 ounces of sea foam to each gallon of gas to help clean out system from old fuel.

if you stored it with gas in it chances are the fuel system is gumed up and i would use a fuel system cleaner like sea foam lucaus oil's makes a cleaner that always worked on our toys all the time.

not running for a year! You have a varnish buildup in the low end circuit of the carb. You will need to remove the carb and do a full teardown of the carb to properly rectify this problem. SOMETIMES we are able to free up the passages by putting SEA FOAM cleaner in the tank , fill her up with fresh fuel and ride through the tank and it will clear up. SEA FOAM can be purchased at an auto parts store and is sometimes very effective. 1/4 cup to full tank fuel.
