Hello Guys and Gals,
I just bought a 10525.
I've been through multiple carbs in my day, and have found awful float bowls before, but I've NEVER come across this. The needle is molded into the seat. I didn't think this poor boy would ever run after all the crud I found in the carb. The fuel line is still completely plugged. I tried using a long air filter screw off a briggs classic to unplug the fuel line and whatever is in there won't budge.
I'm happy to report I replaced the needle and seat and THOROUGHLY cleaned the carb and the old boy runs pretty good. There is a slight surge but given all the junk in the carb I was happy he started on the second pull...
The needle will NOT let go of the seat no matter what.
