I have an Eclipse reel mower with a Briggs model 5s engine that I like to use and take to shows. Now, at some point I would like to restore this little thing, but the carb keeps me from doing that and here is why. It runs great when it runs, but if I let it sit longer than 2 weeks I have to take the carb off and spray carb cleaner into the end of the the pickup tube and free up the little ball in there. I'll be honest, I've been doing this for 2 years now with the thing and I am getting tired of it. I treat all my gas with ethanol stabilizer and marvel mystery oil. is there something I can do to really clean up that pickup tube? Maybe soak it in something? Is it possible to put in a new pickup tube? I know the tube is sealed in there with a kind of putty and I haven't tried to remove it. Should I get a new carb? Any advice would be appreciated!

I hear that lol.Spent days working on a Briggs model N coil.Needed rewound.In the end I just bought another $25 coil for it.My rewire sorta worked.Had spark but very weak.I must of nicked or cracked the coating on the wire when I was rewinding it.

 

 

My 1st rewind didn't go to good lol.Lesson learned don't be a cheap arse and try to save $15. :rolling:

I would first run some seafoam through it. I had very good results with that product.

also when I rebuild or need to really clean one I soak it with Berryman carb cleaner, (it comes in a gallon)

Have you tried running the engine dry before you shut it off?  Or if you are doing this already, use Sta-bail in the fuel and leave the carb full.  Just a suggestion.  I always leave the carb full on all my engines but make sure I have Sta-bail in the fuel as well.

The fuel pick-up tube was/is replaceable.

 

The original number was B&S # 293700, but I don't know if that number has been superseded.

 

The intake gaskets (it takes 2) were # 27355, and the carb-to-tank gasket was # 27404.

 

The gaskets are available through the aftermarket, but I don't know about the fuel pipe.

 

Check with our sponsors to see what they can offer.

Nice! I think that would fix my problem. What about the Grey putty that holds the tube in? Will i need to replace that as well?

That I'm not sure of its been a while since I had one apart, I think they get glued in place or some just get pressed in from what I remember, this one does come with an instruction sheet

Well regardless i ordered one from you. I have some gray tank putty if I need to reset the new one in where the old one is. I hope this works as I would really like to restore the old girl.
