QuestionQUESTION: I have a snapper 28A707 0122-02 riding lawnmower with a walbro 498026 carburetor I cant find a rebuilding kit for this carburetor, I need a nozzle, the brass screw slot broke when I tried to take it out to clean it
How do I get the nozzle out and where do I get a new one.
Is there a replacement for this carburetor
Thanks in advance
PS I was a engine mechanic in the air force during the viet nam war. 2 tours to southeast asia went to school in jonesboro arkansas
ANSWER: Carburetor kit: Briggs and Stratton 497481 (Replaces 496622).
Carburetor: Briggs and Stratton 498027
You can try drilling the old nozzle. If the slot broke odds are the jet is really stuck. DO NOT use a fluted style screw extractor...you will crack the carb...trust me.
You can try using the tap-in 4 sided screw extractor but you may still crack the carb.
Drilling is the best way but...you may have to clean/recut the threads. Of course you will need special taps for the carb threads...they are not normal fine or course SAE or metric threads...they are a special thread pitch.
With all that, you may be better off spending the money on a new carb. If you can get the nozzle out then I would say rebuilt the carb but if you have to have a machine shop remove the nozzle then I would just get a new carb as the labor cost may be $40-50. Add in a new carb kit, $30-35 and you are close to a new carb price.
Let me know if this helps.
