Golf Cart Forum Questions

If a four stroke, my guess would be bad valves. A compression test is a good idea. But best if you know what the compression spec is for that engine. Otherwise you need to compare compression spec from one cylinder to the next. If more than a 10% differential there is a problem.

The noise from behind the flywheel sounds like a bad bearing. But that will not prevent it from running...unless it is seized bearings.

If a 2 stroke motor, then likely bad crankshaft seals. Or maybe a clogged exhaust system.

Evening,

Go back to basics. Compression test would be first. They can be borrowed from your local big box auto parts store.

This is what I posted:

I have a 97 EZGO Gas, but not sure which model. It has the 295 engine. When I got it, the engine was seized. I put some diesel in each cylinder and left it for several months. A few weeks ago, I took the plugs out, made sure it had oil in it, and put a wrench on the flywheel nut and gently turned, and the engine turned. After one turn I was able to spin it by hand relatively easily. I then used a battery to turn the engine over slowly with no plugs. Then I put it up on ramps and changed the oil. It was pretty dirty, and a few particles of metal shavings, but only a few. With fresh oil in, I put in plugs and tried to start it. It started right up once I put in new fuel, but would only run when choked. Today, I took the carb off and cleaned it all. Once back together, it started right up and would run without choke. It seemed to accelerate quickly then run quietly at a medium speed. I assume that is due to the governor. I then took the family for a ride, we got a few blocks away, and it started making a large tapping sound, but only at full speed, at slow speed it seemed to sound normal. I came home and was checking it out. I still haven't found where the sound is coming from, I need to put it up onto jacks to run, but it almost sounds like its coming from under the cover that goes over the flywheel. However, while troubleshooting, I tried running with just one plug at a time connected. I found that it doesn't run with just the driver side cylinder is connected. The plug has spark. Not sure where to go next.

Could it be valves? Rings?

I'm open to suggestions...

THanks,
Brian
