I have a 1986 club cart
I bought a club car 1986 with the flat head motor it was running had a little nap to address it around the block and it just quit you push the pedal the motor still turns but dont start seems like it lost compression
First thing that I'd check is to see if it's getting fuel. Check the fuel filter as well. You'll need to narrow down if it's a spark issue or a fuel issue. Fuel issue= take hose off at carb or if you can see filter and it's a clear type, look to see if fuel is moving while someone try's to start it. Spark issue= Use a pair of pliers with rubber or insulated handles and pull off the spark plug wire and hold it about 1/4 inch off of the head or block. Have someone crank it and see if spark jumps across.
See if one of those are the issue. Good luck.
