I call BS on blaming CARB/EPA for carburetors NOT being rebuildable. Carburetors kits are available on eBay as are new carburetors. $600 to install a NEW carburetor is close to robbery in my book. They figure if you can afford the rig, you can afford the repair bill
I have torn down and cleaned many small engine carburetors, 4 in the past 2 weeks ! If you are careful and don't ruin any gaskets, NO REBUILD KIT IS REQUIRED !
If you suspect bad fuel, before reinstalling a fresh carburetor, empty the tank, rinse with fresh fuel and install a new fuel filter.
Get me the EXACT model number and I will bet I can find a kit/gaskets.
Well, as a technician for a former Onan service center, we were told DIRECTLY by Onan 25 years ago WHY ONAN does not have rebuild kits and WHY the Carbs are replaced and not fixed. While you "may" be able to find rebuild kits on E bay, they are NOT Onan OEM kits. Onan does not have or sell rebuild kits for RV Gensets built after about 1993 or so. Doug
Have you ever considered that they MAY have told you that the carbs "sealed" are not rebuildable so they can simply sell a NEW carb? Especially if you are being paid under warranty, they don't want to pay you for any additional labor.. Cheaper for them to replace parts rather than troubleshoot and fix..
Even Honda carbs suffer from clogging and ARE "built" to EPA specs and rules but yet they can be disassembled and cleaned.
If there is a screw or snap holding the fuel bowl or in some cases the top of the carb in place then the carb CAN be torn apart and cleaned.
EPA has nothing to do with how the carb is put together, what the EPA stuff means is the carb has NO MIXTURE ADJUSTMENTS or the adjustment screws are LIMITED with plastic limiters.
I suspect the problem with the OPs carb (and is typically what happens with any carb) is the MAIN JET has clogged and or the jet nozzle tube above the jet (nozzle tube goes up into the carb throat and has several tiny holes).
You need to be able to get to the main jet and SPRAY carb cleaner through the jet until the dirt has cleared..
I HAVE delt with this on HONDA carbs, on Honda carbs (and pretty much any bowl type small engine carbs) the main jet is hidden inside the center of tube that runs down to the bottom of the fuel bowl.
The fuel bowl is held in place by a screw at the bottom of the fuel bowl.
Remove the screw (don't drop or lose it!), remove fuel bowl..
On Honda carbs the jet IS REMOVABLE and is held in with a screw inside the tube. You need a wide FLAT BLADE SCREW DRIVER the is wide enough to go up the tube and catch BOTH SIDES of the screw.
CAREFULLY unscrew and allow to drop down (the entire jet assy with a additional tube MAY drop down (DO NOT LOSE ANY PARTS).. Observe the order and direction of the parts so you reassemble correctly!!!
Then you can spray out all the little fine holes and reassemble.
Not hard to do.
Now some small engine carbs the jet IS non removable from that tube, those do present a challenge to clean but it can still be done.
HERE is a You tube video link that shows a Honda GX series small engine carb being cleaned.. Pay close attention to the little tube around the 2:28 mark , that tube IS where the clog most likely is..
Poke around the other links that come up on that You tube page for videos with commentary..
While that video shows wire cleaners, they are not needed, often several good blasts with carb cleaner through the tube will dislodge the clog.
ALL the little pin holes in that tube MUST flow, otherwise the carb does not function correctly.
What sets the Honda carb apart is that brass tube is removable making the cleaning easier, many are not.
