I HAVE REBUILT MY CARB AND HAVE BEEN THROUGH IT 7 TIMES CAN'T FIND NOTHING WRONG YET ATV STILL WILL NOT START. I CAN'T REMEMBER HOW THE 1/4 HOSES ON THE CARB WERE. BUT I THOUGHT THEY WERE VENT TUBES ONLY FOR THE FLOAT BOWL. SO I JUST RAN THEM TO NOTHING. RIGHT? GAS GOES IN THE FLOAT AND PUSHES AIR OUT THROUGH THE VENTS AND BOTH OF THOSE ARE JUST VENTS, OR SO I THINK. IF I'M WRONG PLEASE ADVISE. HAVE HAD ATV TWO DAYS BOUGHT FOR MY DAUGHTER AND WE ARE GOING TO KY TO RIDE FOR A WEEK ON THE 19TH, SURE WILL SUCK IF I CAN'T GET RESOLVED BEFORE THEN...

THANKS

 

What is it doing when you go to start it?
Is thier gas in the carb?
Does it have a gravity fed carb or fuel pump?

 

Vent tubes run up from carb ok,sounds like you are ok there,do you have fire,compression? also did you hook vent into bowl drain? Have had customer do this and would run only short time,before starving for air? I run vent lines straight up and tie to throttle cable. also is plug wet? May have too much gas in crank,10 mm drain screw under engine in center. Drain if necessary,hold throttle wide open to clear remaing fuel when starting. Good luck

 

did you check compression yet? should be over 100 psi for it to run good.

 

YEA I'VE CHECKED GAS, I HAVE TAKEN THE CARB OFF 7 TIMES, FLOAT BOWL FULL EVERYTIME. IT IS A GRAVITY FEED CARB. I HAVE TO PULL START IT AND ACTS LIKE IT WANTS TO CRANK OVER BUT IT NEVER BUSTS OVER.

I'LL CHECK THE COMPRESSION THIS MORNING.

THANKS GUYS AT LEAST I KNOW I WAS RIGHT ON THE HOSES BEING JUST VENTS.

 

YOU KNOW THE FIRST TIME I PUT THE CARB ON I DID FLOOD THE ENGINE WITH FUEL AND IT WAS A SEVERAL MINUTES BEFORE IT CAME OUT THE BOTTOM OF THE AIR BOX WHEN I NOTICED IT. I THOUGHT THE FLOATS STUCK SO I REMOVED CHECKED AND REASSEMBLED. I PULLED THE PLUG AND LET IT SIT FOR ABOUT AN HOUR BEFORE I STARTED MESSING WITH IT AGAIN. MAYBE THERE IS TOO MUCH FUEL IN THE CRANKCASE. THANK FOR TIP I'LL CHECK THAT SCREW THIS MORNING AS WELL.

KNOWLEDGE WELL APPRECIATED.

CRAIG.

 

spray carb cleaner.if it runs fuel related,if not...............

 

FUEL WAS IN THE BOTTOM END, DRAINED IT, REMOVED STARTER WHAT FUN THAT WAS!! BY THE WAY I DIDN'T REMOVE ANY CLUTCHES TO DO IT AS SEEN IN COMMENTS FROM SOME OTHER GUYS. WAHT A TERRIBLE DESIGN, NEEDLESS TO SAY THE BRUSHES ARE TOAST AND THE TOP BEARING IN GONE. JUST GONNA ORDER A NEW STARTER. FULL OF MUCH, AND WATER.
