Cost for a new carb

I have a brand new Onan 5500 generator and my fifth wheel toy hauler. It came with 30 gallons of regular gas in one of the 30 gallon tanks. Of course I did not run it as i was suppose to and i'm sure there is a bunch of crude clogging it up so I brought it to our local RV repair shop. 630 dollars to change the carb. Isn't there a carb kit they can use
Or am i being taken to the cleaners?

    That doesn't surprise me, Onan has always been very proud of their parts. If the shop is not familiar with the carb they will just replace it, it will be faster and cheaper than trying to refurbish and hope it works. The repair kit will be close to half the price of a complete unit plus $100/hr+ labor. Is it worth it?


    Has nothing to do with it. 25 years ago California EPA came up with such strict rules that Onan built all their carbs to meet California rules. That means SEALED Carbs. No fiddling with them. So, NO rebuild kits. You RUIN it and you have to buy a new carb. But, they can be removed and disassembled and cleaned out. Rarely will you destroy any of the seals and gaskets needed. Most shops will not disassemble and clean out due to the labor cost. Doug

    Next time just fire it up and give it a go before you take it in.

    If it's just dirty you shouldn't need any parts, just someone to take it apart to clean it. If it needs jets or o-rings they should be $30-40 for a kit if you can find the right one. Worst case I see new carbs in the mid $200 range.

  • Use the forum search feature and look for threads with Seafoam. Carb clogging is common in generators that don't get exercised regularly and many have had luck using Seafoam to remove the "gunk". As far as the cost of a new carb - s/b easy Google if you know the part number.
