dying out

jakeesspoo

The cart had been running good up till a week or so ago. My wife and kids were back in the woods and came walking back The cart will start and go but barely and then just stops and dies out.
It has a new top end with probably only 6 hours on the new top end, points, plug, and new exhaust. I took carb apart and cleaned it then reassembled and problem persisted but then had a gas leak LOL. I replaced carb kit yesterday and also added a electric fuel pump as it seemed like it was running itself dry. I had belt off the engine after I installed the fuel pump and it basically started right up even without choke and sounded great. I put belt back on and took it out of barn and it ran great for 15 seconds then started acting the same. Reeds looked good when I had carb off, I have a awesome blue spark, it seems to be getting plenty of gas judging by looking at fuel filter. Im not sure why it would run awesome for that short time then just die out.... any ideas. My next step when i have time is to get compression reading, check timing, etc. but I would think if points or timing were off it would run like crud initially.....

Your point cam may be wearing down. Check the point adjustment they may be getting too close. Did you put a new ignition coil on the cart? There are some problems with new coils. When it dies quickly pull the plug and see if it is wet with fuel. If it is wet you may be losing spark if it is bone dry you may be not getting fuel when you are suppose to. List all symptoms. Dying out is just not enough info!

Sounds good. Will hopefully be able to look at it more tomorrow. I have the kids by myself all wwekend as my wife works this weekend (RN) My son just turned two last week but i cant take him out to barn with me to work on it cause all he will want to do is ride on it he doesnt understand its broke. As soon as i get home its "golf cart, golf cart" until i give him a ride so its been hard trying to keep him preocuppied from the barn.

You may need more golf carts!

Compression is 105 psi. Gap is correct and timing appears ok. I have the drive belt off. It will run decent for 30 seconds or so and then slowly die out until it will no longer start. At that point if I pull out the plug it appears wet but not sure. Going to go get a new plug. It appears though after I pull the plug out and "run" the engine blowing out the cylinder that it will start up again and then just repeat the dying out cycle. Like I said it did this now both before and after a carb kit replacement a day or two ago and I also added the electric fuel pump. The muffler is brand new and maybe has 5-10 running hours on it.

It is possible that the electric fuel pump is putting out more pressure than the system can stand and flooding the engine. Maybe a small return line to the fuel tank will solve the problem. Or a low pressure electric pump.

Yeah but I had the symptom before the electric fuel pump was added I thought it was starving for gas so I added it. May have to take it back off and try again.

I used the same pump that the other member on here used and I followed his instructions wich included pictures wich was greatly appreciated.

Does working the choke lever have any effect at any time? You may want to check the adjustment on the choke lever? With those manual fuel pumps it's common for people to adjust the choke butterfly to remain a bit open even the knob is showing closed. This helps the engine draw a bit. If this was the case it will need to be adjusted to fully closed when you added the pump.

Almost for certain, when you add an electric pump you will need to dial the carb's fuel adjustment back a bit. Same logic as above, as engine vacuum degrades over time fuel delivery degrades with it. People open the carbs fuel adjustment more and more to account for this. When you add the new pump and fuel flow is more back to normal the carb's fuel adjustment needs redone.

Those pumps are very low pressure. I can stop flow altogether by holding my finger over top of the line. Your carb should be able to handle it with no problem.
