1989 2-stroke no start

[trafficnazi]

My son recently aquired a 1989 EZ Go with a Robin 2 stroke engine. The wiring had been played with alot and who knows what they have done to it. We have fuel, fire and the engine spins when you push the pedal. It does seem a little slow and its the same way when we attach jumper cables. If you remove the plug, it seems to speed up alot. Is there something i'm missing? I tried to find a service and wiring manual to download from the internet but the manuals are higher than the cart is worth. I hate to disappoint him and not be able to get it running but im at the end of my golf cart knowledge.

Welcome to the forum...

I'd start with a compression test.

Thanks for the welcome.
How many PSI should it have?

It should have around 120 lbs...

The older cart manuals are hard to find for download. You can buy them at CartPartsPlus or other online parts sites.
