  • Works flawlessly on new Predator 9000
The media could not be loaded. Installed on a predator 9000 purchased in summer of 2023. This model has the metal airbox and there was zero interference in installation. Was able to run two 1875W hairdryers simultaneously without issue and only the expected draw on the generator. I used 12’ x 3/8 ID airline hooked directly to the carb with a 3/8 barb x 1/2 NPT adapter connected to 1/2 NPT x 1/2 quick connect. Works awesome! ... show more

  • Works on natural gas. Perfectly!!
The media could not be loaded. Was kinda skeptical if this would work on NG since some of the reviews said only “Compressed Natural Gas”. But this is home natural gas that it’s running off of. (Maybe 2psi) and it started up perfect. I did have to tweak the adjustment screw once a load was put on it to bring done the frequency from around 80hz to 60hz. For my particular generator (Ryobi 6500/8125) 420cc model, I had to modify the choke mechanism to work like the default. But if use NG the choke isn’t even necessary. I did try out the gasoline option and it started up fine as well. For the price you can’t beat it I can alway go back to the old carb if needed to. But I shouldn’t need to. One thing that was mentioned in someone else’s review was when using NG, drain the carb bowl of gasoline using the drain valve at the bottom, then close the valve once all is drained. I didn’t try it any other way but doing this did seem to work without any problems. ... show more

  • Worked perfect on a Powerstroke 6000 Generator , install in less then 15 mins
Worked great on my Powerstroke 6000. Installment was less then 15 minutes with no instructions. Even if I had not taken the carburetor off in the past, which I have , it would have been a quick install on this powerstroke generator, as it was a perfect match and fit. One exception on the fit, the fuel line on the original carb was larger then the jet on this carburetor, but it’s an easy correction with a small section on the fuel line. I ended up replacing the last section, about 4 inches of fuel line that goes into the carburetor jet/ nipple to the fuel filter, with a spare fuel line I had for my other generator. I’m also not a big fan of just running the propane to the nipple of the regulator and securing with a clamp, but I guess it will work. Make sure you have , or buy a spare grill to tank hose for the propane tank that you can dissect. For $35.00 and 15 minutes of your time it’s worth the purchase. ... show more

  • Full carburetor replacement - better than more expensive add-ons - but no instructions!
Very slick and a much better conversion than the more expensive ones. It's a full replacement for the carburetor and the choke lever. There are no instructions! But I got it installed in about ten minutes with a bit of thoughtful tinkering. Or you could take it to your local lawn mower repair guy - he replaces carburetors all the day long. You need to attach a propane hose and regulator to attach to a propane tank - I scavenged one from an old barbecue. Attached a fresh tank of propane and the generator fired right up. Propane much cheaper than gasoline(which you can still use in a pinch - it's a dual fuel carburetor) - and propane burns much cleaner than gasoline - better for your generator and for the environment! There are wires coming out the bottom that I suspect is for electric start versions - I plugged them together and stowed them and the thing works fine. ... show more

  • Works perfect with the Predator 8750 WITH SOME SLIGHT MODIFICATIONS!
As many have stated this carburetor is a fantastic item and is actually cheaper than replacing a clogged original carb, plus you get the added advantage of duel fuel use. Win win! There is a slight catch 22 here though if you happen to have one of the newer Predator 8750s like I do. Evidently Predator changed the location of the air intake hose on the 8750 to the back of the air box. Again, as stated the carburetor is a perfect fit but it will require some modifications to the air filter housing. My workaround was to cut the problem air intake “nipple” off the back and relocate it to the side of the box. It is tapered (one end smaller than the other) so I drilled the hole on the side of the housing just large enough to push the small section through from the inside of the air box to the outside. I actually used a heat gun to heat up the area around the hole to make it “pliable” enough to force the nipple through and snug up tight. I also had to use my Drimel tool to shave off a little extra plastic from the back of the housing where it hits the new carburetor. I used JB Weld to plug the hole where the original nipple was. Anyone with just basic handy man skills can accomplish this and there are several YouTube videos that really helped me. I would have probably never attempted the work around had I not seen some of those videos. ... show more

  • Perfect match/fit for the Predator 8750 generator. No modification needed.
Perfect match/fit for the Predator 8750 generator. No modification needed, easy installation. Used a propane regulator off of a BBQ grill, cut off the connector , pushed the rubber hose onto the propane inlet on the carb.. Installed a hose clamp and tightened it down. First ran the generator on gasoline: no problem. Drained the gasoline out of the carb bowel (into a container) via the valve provided, after shutting off main gasoline valve. Opened the carb propane inlet screw one and one half turns out from full closed position. Turned on the valve on the 20 lb. propane tank. Purged the air out of the regulator on the carb via the spring loaded brass screw. Hit the starter switch ( I have a battery installed) and it fired right up. Nice having alternate fuel source possibilities. ... show more

  • Product leaks propane through carburetor
Carburetor was easy to install,done that in about 5 minutes with a pair of plyers. Bad news is it still leaks propane through carburetor first believe diaphragm had a hole in it or was improperly installed,second carburetor still leaks through but not as bad. First on I could hear it leak,second one will flood the carb,use valve on tank,start cranking then open valve on tank,works ok.problem is if engine goes down propane will still leak,kinda dangerous,still need to shut off valve on tank,surprised UL passed it. I needed it and being out side and around generator will use it anyway. Have a second generator and will shop elsewhere should have installed a needle valve that will work but is dangerous,like hipa screw to adjust governor is to short will replace it to proper length. Wouldn't recommend this product to a friend,might to an enimy. ... show more
