Hello. I have an '05 Kazuma 150 KMZ.
My carburetor just started leaking gas heavily through the top "elbow" vent coming off the carbuetor? It pours through even when the motor is off (motor won't run now). It does stop when I turn the petcock off.
Any ideas what the problem can be before i start taking things apart?
Thanks

 

Your float is stuck in the carburator. You can try and tap the bottom of it a few times with the bottom of a screwdriver. If that doesn't work, you will need to take the bowl off of the carburator.

 

Thanks masterbs.
I took the carb apart and it appears that it was sticking. I cleaned everything out and reassembled. It was pretty clean in there though but i figure all it needed to hang up is a piece of sand to stick the float. After reassembly It ran well for about 15 minutes then bogged down and wound not start for about an hour??? Then it started up and now runs fine? Wonder why that happened? maybe the carb is burping though air bubbles?? Just don't want to get stuck on the trails again, it makes me nervous...

 

Check your spark plug you may have gas flooded the motor then had a rich mix that carboned the plug.

 

Thanks. Seems to be running fine this last week. I have not pulled the spark plug to check but i will get a new one seeing that its old now. I got to move on to deal with other pressing issues now. My front end is about to fall apart. Need to start looking into getting balljoints and tie rods etc. wheels seem close to falling off, yikes!

 

my front end loosen up a little on my kmz150 also, all i did was just pull the cotter pin and retighten the nuts for the ball joints and everything seens fine now, this was done appox 6-8 months ago,

 

Thanks! I will give that a try. I have yet to dive into the mess to see whats going on. That would be nice it thats all that's needed! ball joints seem very very loose. I see cotter pins on the tie rods but not on the ball joints? I can see where you can tighten the tie rods but not sure how to tighten the balljoints? It is tight where it goes into the steering knuckle.
Thanks

 

My Redcat VX150 was like yours and Bills. Had to pull the keys and tighten the upper and lower A arm joints, ball joints and the rear and front wheel castle nuts after about 2 weeks of running (40 hrs). China quads have to be checked and tighten every couple of weeks as do other quads. Blue lock tight on bolts and nuts helps, don't use red leak lock. It sticks too good.
