G16 compression test
I did a compression test on my new (to me) golf cart. Not sure if I'm doing it right but when I install the compression tester and hold the gas pedal it spins and the compression only comes up to about 60lbs. but if I stop and start the starter a couple 4-6 times I can get it up to 105lbs. Do I have 60lbs or 105lbs.
Thanks |

Re: G16 compression test
Suppose to hold throttle open, then 4 compression strokes with the starter. That's the correct way.

Re: G16 compression test
to hold throttle open on a golf cart do you just hold the gass pedal down as it turns over? When I did the compression test I could hold the gas pedal down for a bit and it would't get any higher than 30-60lbs but if I bumped the starter it would go up to 105 forward and reverse....I think my compression tester is good? Thoughts?

Re: G16 compression test
You have to perform the test the proper way to have a comparable base line reading. 285 cc motors are suppose to have 165/175 pounds compression when tested this way. A G16 motor, I don't know if its the same or not.

Re: G16 compression test
G16 are the same, should be in the 155-175 range. Do the test at WOT like Mike suggests, but I would make sure the valves are set correctly first ( four thousandths cold). If it's still low squirt a little oil in the cylinder and re-test. If the compression comes up you know you need rings, if not you may have a stuck or bad valve.........

Re: G16 compression test
The genuine Mikuni pump is probably your best bet...

Re: G16 compression test
Yep, factory fuel pumps very rarely give any trouble at all.
