Suzuki Quad Runner

1992 Suzuki Quad Runner 4WD

My ATV will start right up but then it will shut down when I hit the throttle. I recently installed a new carburetor and clean out the gas tank. Any suggestions?

Pull the plug and see what it looks like right after it shuts down. Completely dry means that it probably is not getting enough gas. Should be able to play with the choke and keep it running, but it will run like crap until you fix the real problem.

Wet means it is flooding out.

My guess is the main jet or the needle.

The clue here is "new carb" and "cleaned out the gas tank."

When you clean out a gas tank, there is often some debris that didn't come out or got dislodged as you were putting the tank back on.

Another possibility is a kinked fuel line. Only lets a little bit of gas through, enough to idle, but as soon as you need more it starves the engine.

Thanks, I also replaced the spark plug and the air filter. I will look at the spark plug again.

I check the spark plu and it looked fine. I also changed the air filter. HELP, any other suggestions!!

Whatever you do don't buy a new carb, unless you like to get taken to he cleaners or spend a lot of cash. A new carb can run your anywhere from $300 to $500 new. What i recommend you do is take the carb out and give it a good thorough cleaning. If you want you can try this method which a lot of members say works great:
( Home brewed carb cleaning. ) After you've done that buy yourself a carb kit and install it in your carb. Also make sure the float in the carb is set to spec as well.

Also, Carb rebuild kit is $15.95 US on DennisKirk.com.

I also purchased and installed a new Mikuni ($300+) carburetor and I am still having problems. This ATV is killing me $$$$$$$

Ah, got lost in the conversation...

You need to figure out if it is getting too much fuel or not enough. Typically if it idles fine and then dies when you give it throttle it is not getting enough.

Thanks for all of the feedback. When the carb was replaced the ATV worked fine but the problem(s) just recently started. Does anyone know what the float spec should be for a 1992 Suzuki Quad Runner 4WD - 1992 LT-4WD? Any other suggestions would be appreciated. This ATV is making my hair fall out!!!
