## Questions & Answers

**Q: si es ms rentable usar gas  lpg o gas licuado que gasolina, cual es mas rentable?**
A: Dear Emilde,
 The Kuupo carburetor is Dual Fuel Carburetor for LPG CNG.

**Q: Will this work on a Wen gn625i which is an inverter model?**
A: U need to contact the seller

**Q: Will this fit a champion 100496 generator**
A: YES IT WILL. IT SAVED ME OVER 250$ BY CONVERTING OVER MYSELF. THE SMALL ENGINE REPAIR SHOP WANTED 275$ FOR THEM TO DO THE WORK. I DID IT IN 30 MINUTES AND IT WORKS GREAT !! YOU HAVE TO FIGURE THE CHOKE SETUP. I HAD TO CONVERT THE CHOKE BY USING THE LONGER BLACK PLASTIC PIECE INSTEAD OF THE CRAZY CHOKE CHAMPION USES. GOOD LUCK AND STAY SAFE .

**Q: What regulator is needed for the Propane bottle**
A: All you need is a standard propane regulator, like on your barbecue, nothing special. These can be bought at most home improvement stores, hardware stores, as well as at harbor freight or on Amazon.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Works great
*by C***R on November 24, 2020*

The dual fuel kit was a direct fit for my champion 7500watts 439cc generator and it works great. Hope that helps pics attached. The fitting at the bottom for the gas input is screwed on 1/4 npt, it’s not a press fitting but it has some glue/sealant on it I took the gas regulator apart and heated the fitting with a heat gun and made some adjustments as to where I needed to point for the hose not to hit the tire I used fuel line hose and a 3/4 inch quick connect kit to make it so that I can connect and disconnect hose from generator with ease and switch between gas and propane. worked out great. Hope that helps

### ⭐⭐⭐⭐ Fit my Generac GP7500E (2015 model)
*by M***C on February 23, 2021*

It works... okay... as long as you have an electric starter. I've found pull starting on propane is basically impossible. Up front, I'll admit there's a 50/50 chance it's user error and I have an adjustment off (but how would I know? there are no instructions included!), but I've fiddled with the screws and it doesn't seem to change anything related to starting.Helpfully, there is a "push button" with a spring on the large regulator that will "prime" the carburetor (it just allows propane vapor directly into the carb without vacuum) - I've found that holding this in WHILE cranking the starter for 5 seconds makes it easier, but it always takes a few tries to get it going, with or without choke. Once running, it works great. I haven't fully load tested it but it should easily serve my purposes.The carburetor otherwise works just fine on gasoline - I can often pull start in one attempt. But, the gas tank is off the generator and probably won't return, so that aspect is basically irrelevant to me. The reason I want propane at all is because when I need the generator I'm either out of gas or the gas in the tank has gone bad. Propane stores forever.Install on the Generac GP7500E: I didn't need to use either of the plastic "spacer" plates and only used two of the gaskets for my application. I found the choke lever very confusing until I realized the tiny pin is metal - it's much stronger than it looks to my old eyes. Also worth noting that, like the other reviewer, I wanted to replace the inlet barb elbow fitting on the bottom with a 3/8 male flare so I could easily connect an off-the-shelf barbeque regulator and hose, but alas, either mine was different than his or I did something wrong (I wasn't willing to use a heat gun like he says he did). I was able to turn the elbow with a wrench with real effort, but it just spun in the housing. A little bit of white dried glue-ish looking stuff crumbled out from the joint, so I'm hoping I didn't ruin a seal, but the pressure is so low (about 1/3 psi) coming from the tank's regulator that I think it's fine since it will only be pressurized while in use. The attached photo shows the hack job I did with some clear flexible PVC tubing and some hose clamps because I wasn't willing to cut my propane line. I really wish that barb elbow was threaded in/removable!Overall, it does the job, so 4 stars, but it's also forced me to finally replace the generator's battery and failed starter relay since I've been getting away with pull starting for years on gasoline. Perhaps I'll figure out how to tune it better so I can pull start, in which case I'll return and describe what I did. Good luck everyone!

### ⭐⭐⭐⭐⭐ If it fits might b good
*by A***R on June 9, 2023*
