Is it the Carburetor or Fuel Pump? - Golf Cart Won't Run or Runs Poorly - How to Fix
Вставка
- Опубліковано 23 сер 2021
- In this video you will learn how to diagnose and fix a fuel problem from the gas tank through cleaning the carburetor. There are many reasons why fuel may not be getting to or through your carburetor to the engine so it can cause the engine to fire and run.
I will walk you through the process I took with this Yamaha Golf Cart to find out why it would not run and ran poorly.
After checking and repairing the fuel filter, fuel lines, fuel pump and cleaning the carburetor the engine runs like new!

I was very impressed with the easy to follow steps on the reinstallation of the carb, but I was not happy with the way it was taken apart, so when I saw the way you put it together I was very happy, thanks good job
I try not to take too much time to get the directions across. I thought showing more details on the reinstallation would give people the details they would need to do the job themselves. Glad it helped
Love videos like this. Thanks for sharing.
Thanks for watching!
I notice you didn't pull the pilot(Big screw in middle) out and clean it. The second time I cleaned my carb, I opt to soak the pilot and other parts in a shot glass of carb cleaner and it pulled out some nasty stuff that was missed earlier.
I got a ezgo it will run but when going up the hill it have a hard time running what could be the problem
Greetings, I have the same golf cart as in your video. 1985 Yamaha G1. Owned this cart for about about 7 years now; I use it on a 4-acre farm property. About 2 weeks ago, I failed to check my fuel level and ran out of gas. From that point to the present, I have had the same issue as in your video with no power. I followed your video to check the carburetor at the fuel bowl level, but I still need to remove it entirely as you did. There was no debris in the fuel bowl; I sprayed carb cleaner and reconnected, however, to no avail. I sprayed carb cleaner in the jets, motor kicked in with full power, then slowed down. I followed another video to check the fuel line from the tank to the pump, and all was clear. As you showed, I checked the line from the fuel pump to the carb, and no fuel was coming out. So I ordered a fuel pump from eBay, which I discovered was my first mistake. The fuel intake brass nipple is a smaller diameter than the original "mic" brand, I had to use a hose clamp to secure the hose; the screw pattern is off about 1/16" smaller than the original; holes on the device I needed to drill out to accommodate the size of the screw to fit the frame. The unfortunate part of all this is no fuel is pumping out from this device. I stated all this to ask the question. Is there a way to test a fuel pump? I believe I need to purchase an OEM fuel pump, do you agree? Thank you!
It is a little difficult to follow what you have written without looking at it. When the original fuel pump was on there did you check the fuel filter and everything else From the fuel tank to the carburetor? When you ran it out of fuel maybe something got clogged or the air in the line interrupted fuel getting to the carburetor?… Your new pump being the wrong size and using hose clamps sounds like there is a chance of air getting into the line without a good hose clamp to seal it. If it were me I would go back to your original fuel pump and see if you can diagnose the problem from there.
Maybe running the fuel tank empty pull some debris into the fuel pump or fuel filter?. The way that your fuel pump works is by the piston causing the diaphragm and the pump to pump the fuel into the carburetor. To test your fuel pump you press the Excelerator like I did in the video with the fuel supply line to the carburetor disconnected and you should see fuel pumping out of that hose. If you’re not getting fuel coming out of that hose it’s because of a cracked fuel line or a clogged fuel filter or possibly a clogged or bad fuel pump. It is hard to diagnose without looking at it.
@@helpinguonline Greetings, sir; thank you for taking the time to reply. Apologize for the delay in responding back. I did check the fuel line from the pump back to the tank in two methods. I removed the line from inside the gas tank with the hose connected to the fuel filter and the hose connected to the metal line. I disconnected the hose between the end of the metal line to the fuel pump. I applied a small amount of air to the line from the tank with a compressor. The fuel in the filter and line blew out and cleared the line. I then placed the tube back in the gas tank and connected the hose between the metal line and the fuel pump. I then pressurized the fuel tank with compressed air, and fuel filled up the filter and line. I started the motor, but to no avail; fuel did not come through the pump. I do not expect you to respond, sir; just letting you know of my steps. Thank you.
It is hard to say without looking at it.... but... sure, your fuel pump could be bad or an obstruction somewhere. Is the fuel you put in the tank good (no water in it?) If everything is clear to the pump and the pump isn't working replacing the pump would be a good guess...and you need air tight connections for the pump to work properly. Sorry I can't be more help... but you will get it if you keep plugging away at it.
Let us know what you find and how you fixed it.
I've got an 87' G2 four stroke and with the instructions from your video I now have a really clean carb. Thank you - but my initial problem persists. It runs so rich other cart drivers stay about a quarter mile behind me! I can't find any advice on the problem. Can you point me in the right direction, please?
Make sure your air filter is clean...
There is a fuel adjustment screw on the carburetor if it is running too rich you can try adjusting that (turning it clockwise will provide less fuel to the carb.
Is it running rich or burning oil?
Let us know what it was after you get it fixed.
@@helpinguonline Installed a new filter/pre-filter and not quite as bad but not much better. I've had to run it using 1/4 choke to get it to run smoother and get more power. Not burning oil or smoking at all.
Fuel mixture screw is set at 1 & 3/4 turns out right now. I really appreciate that you respond to requests for help. It's one of the reasons I subscribed.
If you have to run it with 1/4 choke that means you are not getting enough fuel (it's running lean not rich). turn the screw out (counter clockwise) further and see if that helps.... check fuel filter to see if it is clogged if so install a new one. check fuel pump and lines to make sure no leaks and all working well.
your carb needs more fuel not less if you have to run it with the choke.
Let us know what you find and how you resolved the problem
@@helpinguonline I've adjusted the mixture screw outward as much as 1/2 to 3/4 turn and though it no longer requires running with the choke open 1/4, the fumes are still nearly unbearable. I'm leaning towards getting a new carb. Thanks for your help.

I have a g1 yamaha 2 stroke it will Starr up and run but it has no power like I can have the gas pedal to the floor and it may go cpl miles an hour! Any thoughts on what the issue might be?
I do not have enough information to be able to diagnose your problem but… Is it getting enough fuel?… Is it getting enough air?… Is it running well but something as simple as the brake is sticking?… Did you run it on straight gas without two cycle oil and score the piston and Cylinder wall?… I would start simple and work your way deeper from there. Let us know what you find out
Is this a g1? I have the same cart with similar problems but previous owners have gotten rid of all the serials
Yes it is
I recently had a 2001 Club Car DS serviced for a no start problem. A new coil was installed, new fuel lines and filers and supposedly the carb was cleaned by the serviceman. Now it is slow to get started...you can only press the accelerator down slightly to starts then it run roughly and finally after a couple of minutes it runs fine. The fuel pump is pumping fuel but can you have one failing do this or any other suggestions? Thanks for your time.
Sounds like your carburetor needs adjusting. There should be an air / fuel adjustment screw on the carb to do that. Also, the choke may be opening too soon before it is warmed up enough to run smoothly.
@@helpinguonline Would the carb need adjustment even though none of the screws were touched. He did suggest putting Seafoam in it and run it but that didn't make much difference.
I thought you mentioned that it was serviced and had the Carb cleaned. If it was cleaned, it would have been disassembled. The air/fuel screw would have been removed and reinstalled. Thus, it may need a little fine tuning?. Takes just a minute to do. You should be able to find a video online to show you how to do that on your club car.
it also could be a choke issue if the cart runs well when warmed up.
Thanks so much for your help. I will check the choke.
I've got a G1 golf cart that will turn over but it won't drive. Any advice?
Check and see if you have fuel going to the carburetor and if you do then check and see if you have spark. It is probably one of those two things. Those are the most common causes
Is there any way to adjust the speed on those carts?
You can adjust the Governor to make it go faster. There is information on google and youtube on how to do that.
I don't like to do that because I want to get the most life and longevity out of the engine so I don't push it.

just make sure your oil pump is working properly if you want to run this like a snowmobile.
Your valve cover is missing the hose
How do you check the oil in the engine and the transmission
It's a G1 golf cart
Still trying to find out how to check the oil in the G1 2 stroke golf cart and transmission do not see any dipsticks
😮
@@jefferylee7550it’s a 2 stroke. No oil in the engine. The oil is mixed in from the oil tank on the side. If the oil pump is bad, you can premix the fuel with 2 stroke oil. Also, no fluid in the trans. It a centrifugal clutch. Take a look at it and see how it all works.
A new carb on Ebay is under $20 delivered.
Don't give up on your Japanese carb for a Chinese one.
I have a G1. New fuel pump. Vacuum coming from the crank case. Fuel will not pump. Any advise?
Is your fuel line kinked? Fuel filter blocked? Properly hooked up? Is your fuel pump working even though it is new?
I would start with the simplest thing first and work your way through it.
Let us know what you find.
For being stored for 4 yrs that's damn clean... lmao
My 2009 club car won t do anything, battery good step on gas nothing, suggestions. PKEASR
This may help...
