Re: Having trouble to get it running it fires but wont...
Choked? bad gas. gas sitting for only a few months will go bad. Spray some WD40 into carb and try to fire. if it runs replace gas. Check to be sure keyway has not slipped

these ATVs do a lot of hard work for size of motor
worth checking other things as per normal servicing
new spark plug
clean air filter
drain and add new fuel to tank
wont hurt to clean the carby or bowl contents
if fitted with a fuel filter inline .. fit a new one
Check that the fuel pump is working and pumping fuel (fuse or burnt out) as it sounds like there is no fuel in the carby. To check if the engine is going to run remove the air filter from the top of the carby and pour about a table spoon of fuel directly into the carby throat. Replace the air filter and crank the engine. If is going to run it will fire and then stop
Remove the filter or filter connection to the back side of the carb and spray it with starter fluid. If it starts when you do that each time, the carbs still have a problem and need to be cleaned out again or adjusted correctly.
You can check for spark and a cloged carb at the same time dump a lil fuel straight down the carb if it kicks theres spark if not well... you could double check the firing order and timing good luck on the Fixed Or Repaired Daily :p
it sounds like a fuel problem.
first drian fuel out of tank.
i know you have already cleaned the carby but dis assemble carby and clean with carby cleaner.
re assemble carby & fill tank with fresh fuel.
also clean air filter & check oil level & check spark plug,if the spark plug is black and the tip is blocked with oil build up, then replace.
squirt a bit of aerostart in the air cleaner, if that makes it run its a carby fuel problem, if that doesnt make it fire, do compression test, check valve clearance , valve timing
If you have a spark, but weak. It is possible that your flywheel is demagnetised. Then you'll need a spare.
If sparks are good, then the spark plug should be moisted with fuel after a few ( 10 ) choke kickstarts. If so you'll have a weak compression. Then you have to at least clean out the piston ring grooves ( dismount cilinderhead and cilinder ), or even change the piston rings or overbore the cilinder and place a new oversize piston kit.
If spark plug stays dry when kickstarting, the carburettor is faulty. Clean it out, check also the choke system. Check the air intake between carb and cilinder for air leaks.
