G1 starts and goes well, but after stopping is hard to get going again.

I am helping out my son's high school baseball team. They use the cart to drag the baseball infield.

They mentioned that it hasn't been running well and is hard to start after it has stopped. If they wait 5 minutes it will go again.

I took the bowl off the carburetor, and it didn't look dirty. The fuel shutoff float pin had a ring around it where it seats. I cleaned it as well as I could with my fingers and re-assembled. I also checked the plug. It looked normal, not black and gunky. The air cleaner didn't look too dirty.

Went for a drive and it goes well at full throttle until you stop, and then it is hard to get going again. I tried pumping the throttle pedal, pulling the choke... and then it randomly revs up and starts going. I suspect it is the starter motor turning the engine till it starts, and not the engine idling (after reading in these forums). How to tell if the engine is idling or the starter is turning the motor? It is a little strange that it shuts off if the throttle pedal is not pressed.

I checked the fuel level and it was pretty low, so I put more fuel in. Same behavior.

I was looking around in the engine area looking for something wrong, and found a crack in the hose from the crankcase to the fuel pump. Still same behavior.

I was thinking it is the fuel pump not working well until it gets going and then it works well at high RPM, but not sure how it gets started.

TIA

(They also have another cart that is not working. Seems to not be starting. It looks like a newer model, but I will focus on one at a time.)

On the G1 it could be a lot of things.

The right thing is to check compression. These engines are notorious for having leaking crank seals, this causes a loss of compression and running issue. Also look around the crankshaft area for oil drips, this is a sure indication of worn crank seals.

It could still be in the basics. Check spark, check fuel delivery, clean the carburetor jets with carb spray. Don't try to run it on ether/starting fluid as this can damage the engine on a 2 stroke. If it won't run on good clean gas, somethings wrong.
