It would not even fire a bit without spraying starter fluid into the intake. It would rev up for a second and then die. I noticed that the choke butterfly was not closing, so I needed an new automatic choke. When I tried to remove the main jet, the slot had gotten so buggered up that it could no longer be removed, so I ordered a whole new carb. Replaced both the automatic choke assy and the carburetor. However, it behaves exactly the same way as before. I checked to see if the bowl was filling up, and it was. I checked the throttle linkage, and it is opening the throttle up on the carb. How can the carb jets be clogged up from the factory? Any ideas?
