I took the carb off the YZ426 today to clean it up and try to eliminate the part throttle stumble. I took out the Hot Start plunger and noticed it was bent right where the black rubber seal begins is this normal? Should I try to straighten it? It is just on the shaft part about an inch or so below the red button. I noticed the choke was the same way. Also the Hot Start button wont stay pulled out it just keeps popping right back in is this normal? Thank you for your time.
