Small Engines (Lawn Mowers, etc.): No Fuel to engine, head bolts, stale gas

Question
Eric
I have checked all the bolts and they are tight, I had my hand over the carb and it still would not start, So I took it apart again and cleaned out every port I know of. It finally started and it ran crappy and surged at this point I will get a new carb as I belive the carb has problems and as cheap as they are  and the snow coming up it is best not to mess with this any more as it is not worth the time. I appreciate your help. OBTW I am a expert here on the  AllExperts Electrical Wiring in the Home Forum so If you need any help just let me know.
Thanks

Ben

I have a sears Snowblower with a B&S Model # 09A413 Type 0202 Engine. The fuel is clean the tank is clean the snow blower is less than 8 months old. The engine will not start untill I spray gas into the intake of the carb. It will start for a few than shut down. I have taken the carb apart and cleaned out any garbage there may be in the Carb I blew out with air the bowl,the choke and all the other orifices I can think of. The bowl fills up with fuel and when I try to use the primer bulb it sounds like I am not getting any fuel to the intake. You think I should have sears get me a new carb. When I went there they said I had stale gas. I replaced the fuel already, I pretty well know some things about small engines but this sounds like a bad jet or a clogged fuel port. Can you give me any more help?

Thanks GB

Did you check the intake screws and gaskets?  Sometimes the screws vibrate loose and cause the gasket to leak.
There is a remote possibly you may have a head gasket leaking or valve issue.  Make sure the head bolts are tight.  I say this is remote because it starts when the engine is primed.

If the intake screws, gaskets are tight, the head bolts tight then the problem has to be in the carb.
Can you place you hand over the carb throat and start the engine?  This will block all air to the carb forcing the engine to pull fuel from the carb.
Let me know.

Did you try running a small wire through the orfices?  Briggs does not recommend this as some people have damaged their carbs but if you are considering a new one anyhow it would not hurt to try.
We use a small tag wire or you can use some 12-14 gauge braided wire.  Strip the insulation off the wire and then use one of the small wires to poke through orfices.
Make sure you use carb cleaner and compressed air from an air compressor to clean out any debris after you run thr wire through the orfices.
Let me know if this helps.
