I have a Weedeater Model 500 with a Model number of 96114001502. It appears to have the springs that control the carburetor not placed properly as they do not seem to control the fuel flow very well. The engine will start but seems to be running very rough with puffs of black smoke coming out the exhaust. I would like to get a picture of how the springs are supposed to look when placed right to compare with what I have.
