Unless you drained the tank and carbs when you put it away for that length of time you are going to have to strip and clean the carbs out. Unfortunately as petrol evaporates it leaves a varnish type material behind. Over time this will build up. Carbs run on very fine tollerances so you are having rich running issues. Probably one of the bypass circuits is clogged. Time patience and plenty of carb cleaner I'm afraid then run some in-tank cleaner through for the first tank or so. Good luck.

Carburetor is probably gummed up. Try running some "Sea Foam" in your gas, run it until the mix is in the carb and then shut it off and let it sit. I had to let a snowblower sit a week until it dissolved all the gum. If your using gas with Ethanol, this is a common problem. Try finding a station that sells gas without Ethanol or use Sea Foam to keep the Ethanol from breaking down. (It can break down in as little as 30 days).
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
Thee new fuels today go bad after around 3 weeks because of the ethonol content. Put a can of Sea Foam in the gas tank see if that helps clean it out. Best bet is to drain the tank put new fuel in it with a can of Sea Foam, then give it a good long run until the tank is empty. Re fill the tank and put the correct amount of Stabil in the with the gas, this will stop the gas from turning into sugar and it works for years.
Hi ! a easy way to possibly help this is to get a can of sea foam at the parts store and dump it in your tank it may help dissolve any goop that is in there and it helps renew bad gas ,also if this does not help remove your fuel filter and blow through it it may now have gotten a bit gumped up ,not a bad idea if you havnt done that for a few years anyway ,mostly the sea foam should help!
Check the intake manifold/s, even a small leak will make it run poor. Being stored for five years then putting it into use, you may have a blocked main jet. Sea-foam is a great product and I would have used that product to store the bike but not to get it running. It is slow acting so it doesnt work like carb cleaner.
Hi... I have a Poulan PRO Quantum xnp 6.75. Garage kept, unused approximately 2 yrs. Added fuel, primed & mower started but then shut down immediately. Then fuel began leaking from the primer button. I'm a single mom & CANNOT afford to have anyone fix this. However I am attempting to repair myself. PLEASE.... If you have any suggestions &/or solutions I would LOVE to know.
