I am just wondering no one ever replaces the needle seat in the carburetor. I have a GX140 on a tiller and the carb. is overflowing, when my nephew brought it to me you could smell gas in the crankcase oil, I cleaned the carb and put it back together and a little while later the carb is overflowing again. Will take it apart again today

Hi John,
The Needle seat is not replaceable on these types of Carburetors. You can however replace the needle itself. Check the tip of the needle, they are made of a soft material so if the tip of the needle has gone hard (as they do over time) you will need to replace it. If you are still having issues with the Carburetor after this, please send me an e-mail with your phone number to [e-mail] and i will give you a call. Cheers - David

@@melbournepowerequipment3441 great info. I was wondering this exact thing.

[@alejandrocuellar15]

Is it possible to remove the bowl arms attached to the carb without breaking it?

[@melbournepowerequipment3441]

Hi mate, is it the arms holding the float in with the pin that you are referring to? If so these are next to impossible to remove without breaking (i have tried 😂), as they are a non-serviceable part of the carburettor and are press-fitted in with plastic locking tabs. Cheers - David

@melbournepowerequipment3441 I thought it was pressed in. I thought maybe someone has been able to. But like you say you'd basically end up breaking it. You can't even buy a replacement seat. I was wondering since I was trying to remove all the plastic parts so I can soak my gx 390 carb in pinesol. I heard that the pinesol would eat away at any plastic pieces. It goes to a hot water pressure washer.

[@melbournepowerequipment3441]

You are spot on that part cannot be purchased. A good clean out with Brake Cleaner / Carby Cleaner should do the trick, it dilutes and removes bad fuel contaminants quite easily. If that doesn't work, we use an ultrasonic cleaner with a carburetor cleaner that's safe on plastics and aluminum, they are the best options I have found so far!
