1:10 is the idle screw. Everyone make sure you turn that screw clockwise (count the # of turns in) until it bottoms out BEFORE your remove it so you can put it back in the same position when you reinstall it. When running, you can increase the idle by turning the screw clockwise and decrease the idle by turning the screw counterclockwise until you have it in the sweet spot. 1:35 is air jet which is known as the air mixture screw in other carburetors. The pilot and main jets are inside the carburetor (bowl must be removed).

Or you could just re calibrate the idle but thats if you know how to do it even tho it isnt that hard some people might not know or want to do it so just count the number or turns or take a sliver sharpie and draw a line over the head body and carb of the screw and line it up with thoose

Nice! This is so important. I do it all the time now. 3:27 "Everyone thinks this thing is starving for air but what it's starving for is gas." mic drop.

I tried this fix to my surging Predator, and now no more surge. Fantastic !!! Thanks

Excellent video. Just got back from Lake Hemet. My predator did the surge and die routine.... Got back and found your video.Cleaned jet, emptied carburetor bowl, did an oil change and spark plug change. generator has been running for hours now with no problem. Also added fuel injector additive to the tank. Heads up to everyone, be careful when you remove throttle screw. Throttle adjustment screw is plastic and find thread.. Need to remove that before removing jet. Clean jet and solves a lot of your problems. But putting back the screw and jet is a little challenge

Man this worked thanks so much. I thought there was no way it could be clogged jet as it was brand new...shot some wd through the jet and voila. Thanks again 👍🏼

I've had this Predator for a year. The most frustrating thing is it would sometimes be smooth, which misled me to think it was fuel related. I had found your video before a recent few night stay at San Onofre and it seemed easy, but while prepping the trailer to leave, it started running smooth, so I didn't do it. Of course at the beach it surged the entire time there, never stalling, but overload indicated every time it throttled back up. O was so afraid of burning up the inverter. Got home, did the fix, cranked it, smooth as the day I got it. Am now draining the bowl after every use, will look for a local station that doesn't have ethanol in the gas. Thanks again dude. 💲

Wow thank you so much. I only had this generator for 1 month and it started surging. This worked. THANKS.

Nice video thanks! A little tip upon startup you're supposed to leave it on the start position until the green blinking light turns solid, then switch the knob to the run position. Not sure if it really makes any difference but thats what the manual says to do on startup. It usually takes 3 seconds for that blinking light to turn solid on mine. I am having the same surging idle issue. I've done this fix once before hopefully it works again.
