Honda lawn mower carburetor leaks badly
I have a Honda HRX217KHMA that wouldn't start. I'm almost certain that it needed a carb cleaning from sitting too long over the winter months.
So I took the Keihn carburetor apart and cleaned all orifices with W-D and blew them out with compressed air. I also removed the jet and did the same.
I put everything back together, turned on the gas valve and found a lot of gas leaking. I couldn't see where it was coming from because the air filter assembly blocks the view of the carburetor. But it felt like it was leaking from the where the bowl meets the carb body. I figure it must be the gasket since I reused the same one although it looked fine.
I took it apart again and made sure there was no gas in the float and that it moved freely, and changed the bowl gaskets. I put everything back together, turned on the gas valve only to find that again, it leaked badly. But I can't see where it's coming from because of the air filter assembly.
I doubt it's leaking from the gaskets since they're new I'd think that any leak would be slow. It's as if the float is stuck and the carb is overflowing, but it looked fine before I put it back together.
A friend tells me that maybe the o-ring where the needle seats fell out during dis-assembly. I can't find a parts diagram for that model, but I checked a parts diagram of a Keihn carb from a similar model HRX217HXA and don't see any o-ring or seat where the needle goes.
Any help would be appreciated.
