Club car XRT dies when I accelerate

Rmiller863

I have a club car XRT that idles great, very smooth. But when I step on the gas it dies. I crank it up, give it gas it dies again.... I've checked the plugs and they're good. I cleaned the carb and the gas is fresh. Any suggestions? Thanks in advance.

I'm not familiar with your cart and motor, but it sounds to me like the accelerator pump function of your carburetor isn't working. With the motor not running, can you look down the throat of the carburetor (where the air enters - air cleaner removed) and see a tiny stream of fuel shoot in as you quickly open the throttle? If you can't see this stream your problem is quite likely a defective accelerator pump membrane or a plugged passage inside the carburetor. A spark advance problem could also be your problem, but this usually results in sluggish acceleration and not cut-out. Can you post the make and model of your carburetor? Do you have a parts list and exploded view of the carburetor?

I'm not sure what type of carb it is, it's a Kawasaki motor , I think it's a 675 cc. I'm not much of a mechanic, but I'll try and see if I can see fuel entering like you say. Could it possibly be the air/fuel mixture isn't right? I hoping I can just clean the carb and that would work? The cart hasn't ran in about 5 years, I cleaned the carb once, but thinking it needs it again. It's almost like its flooding when I give it gas. I can barely hold the pedal and idle around my yard. But if I step on it, it's seems like it may be flooding. As soon as it starts to die, I can let off the pedal and it sputters then goes back to a regular smooth idle.

I did notice that the fuel line on this cart is 1/4 inch line. I have a DS also and it has smaller fuel lines, I think 3/8. Could it be getting too much fuel from a bigger than normal line and it's just flooding it? Thanks

I still think you have a carb problem and still think it has something to do with the accelerator pump. Probably one of the tiny passages that carry fuel to or from the accelerator pump, or the pump itself has bad rubber parts. When you open the throttle a lot of air suddenly enters the motor. If the accelerator pump doesn't produce a quick squirt of fuel into the motor as the air enters, the motor will stall out from a lack of the right fuel/air mixture. The main jet could also be plugged and it's running on the idle mixture alone.

Since your cart hasn't run in 5 years the fuel that was left in the carb has dried out and plugged it up. Only a very thorough cleaning, even to the point of finding these tiny passages and running a piece of small copper wire through them will get them cleaned out. An exploded view that's typically shown with a parts list for your model carburetor will show where these ports are. You will also need this parts list to order the new rubber parts. If you can't find the make and model numbers for the carb it is sometimes helpful if you can post some clear photos of it for one of us to recognize. It would be a good idea to replace the fuel lines and fuel filter as well.

I did replace the fuel lines and filters. I will try and see if I can find any #s on the carb, and try to take pics. I will be out of town for the weekend, I'll try and get it posted tomorrow before I leave. Thanks for the help

I couldn't find any #'s on the carb. But I did clean it very thoroughly before putting it back in.

Now it won't idle at all. It turns over but won't fire? It's getting fuel to the carb, I've taken it off several times to check and the bowl is always full. I checked for spark and it's fine. The plugs look good. Ran sand paper through them just to be safe before putting them back.
I'm almost thinking possibly something electrical. I didn't pay much attention to it before, but when it was idling and I'd turn it off and it still stayed running. I'd have to choke it to shut it down. Also it blew the 10 amp fuse several times out of the blue. I thought that was strange without touching any wires that a fuse would blow?
I went through my trouble shooting and I'm completely stumped. If anyone has had this issue or can offer advice it would be much appreciated. Thanks in advance

holy smoke... a 675cc motor?
carryalls have the 350, very few had the 400, same motor, diffenrt bore.
first off, look at your air box, make sure its sealed and installed correctly. these are picky with ai rleaks. yes you will need to run a air filter in the cart, there that picky.
if you replaced fuel lines, endure they are ran correctly, and the pulse line from the engine to the pump does not have a droop in it, but it has a little flex in it for vibration and drivabilty. make sure your air tubes are tight, not leaking, and or colapsing. 3rd, i would pull the carb, give it a good cleaning, its real easy, pull the carb, pull the bowl, lay it out as you take it apart, take pictures for before and after pictures to help. make sure the main jet is clear, it goes right up the middle, it has 2 holes in the side as i recall, it unscrews, use a piece of then wire, ensure cleaner, and wire go through it. DO NOT DO THIS INSIDE< OR IN A PLACE THAT WILL GET DAMAGED! carb cleaner willl eat paint, and it will eat plastic, if left on two long....just take your time.... no need to adjust any screws, or take any out other then the bowl screw, and the main jet. oy u will have a thin reusable gasket at the bowl nut, as i recall, it has hole in them too, and a oring from the bowl to the body. also pay attention to the direction of the bowl, it has a ridge in it, as i recall, you want the ridge high side on the inside opposite of the float needle.

Did you ever find out what was causing your problem. My club car stated doing the same thing. Cleaned the carb four times and then got a new one, Didn't help. Changed the fuel lines, replaced the fuel filter, checked the pump, adjusted the valves, nothing helps. It start perfect, idles fine , as soon as you push down the gas pedal it falls on it's face and dies, sometimes backfires and
dies. If when it starts to die you let up on the gas it goes back to idle and idle perfect. Compression is 130PSI.
