2- cycle golf cart
I have recently installed a new top half to an old ParCar/ Columbian golf car. Everythink seemed to go together just fine... Now thats its back together, the only way I can get it to roll over is with the spark plug out. As soon as I put in the plug the starter doesn't have enough power to roll the engine over.
Can anyone give me some ideas on what might be up?

First, I'd go through the basic electrical stuff: get a good fully charged battery, clean the battery terminals and connections at the solenoid & starter motor.
I've heard some people talk about a starter going "weak" though I've never seen one personally.

I am with Pilot, you need to eliminate the electrical stuff first. Measure the voltage on the battery, and if it is not close to 13, try a different battery or jumper cables. My battery charger has a 50 amp "starter setting", which helps overcome weak batteries when troubleshooting.

Connect a DC volt meter to the battery. Use should get a reading of anywhere from 12.5-14.0V for a fully charged battery. Hit the starter button while the meter is connected and check volts at the battery. A good battery will maintain 9-12V but a bad battery may drop below that while cranking.
Try checking how many volts are reaching the starter motor. Connect the red (+) lead of the volt meter to the starter motor positive side and the black (-) to a common ground while hitting the starter motor. You should get at least 12V to the starter, if not you have a battery/electrical problem.
Did the starter work fine before the top end replacement? I have seen where the engine will make too much compression and even a good starter motor does not have the power to rotate the engine. You can try a compression check of the engine to conform this. A good engine will have about 150lb's of compression (testing with throttle wide open) I have seen engines with carbon build up on top of the piston where the compression is near 200lbs
Let us know what you find.
