Honda GX160 help..

Hi everyone,I thought I was quite clued when it come to engines but my new (2nd hand) generator with a GX160 engine has me completely stumped. As you may know it has a governor.. why does it lowers the revs when I apply a load/power tool? Surely it should up the revs, right?

Also, the air/pilot screw is 5 turns out, is this correct? If I rev the engine quickly and shut off the throttle it pops on deceleration, could the screw be the cause? My spark plug looks OK.

It's as if the whole thing has been stripped and not put back properly. I've tried adjusting the governor by turning the shaft the opposite way but this just revs the engine into oblivion.

Any help would be much appreciated,
Lou

It shouldn't increase speed, just hold the same speed. Unless you are putting more load than it was designed for. You need a tach of some kind to see what the RPM is actually doing. I don't know what the setting for the pilot screw is.

If you messed with the governor setting, you need to reset it. The governor setting is set at the factory and should never have to be changed.

It sounds like your carburetor is partially clogged and the air/fuel mixture screw should only be 1 1/2 turns out roughly.

Can anyone confirm that the governor is meant to shut the carb off/lower the RPMs slightly when the load is applied?

He never, he said it "shouldn't", I asked for someone who also owns a GX160 to confirm.

I own many of them (without going out and counting, there should be at least 5). It should not. I don't know how that doesn't answer your question? Maybe I am misunderstanding what you are asking. If someone has one that does, then something is wrong with theirs too, because it shouldn't.
