My BG85 has started to degrade in performance and now does not run well enough to continue use. The pattern of "flameout," poor starting, and irregular power (fluctuations in rpms) tell me that the carb has degenerated diaphragms. It seems to me like it is not getting enough fuel. It is 6-7 years old, run daily for the season (mow/blow about 1,200 properties per season), and has been used hard for leaf work every Fall. I wanted to get a G & D kit, but need to know the Zama carb number. Like all STIHL products, the only way to get the numbers is when the carb is off and one can find the stamped numbers on the existing carb. When I went to take the carb off, I found the carb does not slip off the posts because of restraint by the throttle wire. It appears that the only way to slip the carb off the Z-connection at the end of the throttle wire is to rotate it, but this only can happen when the carb is off the posts. Sure, I can take a plier, or some tool, to bend the wire, but I am concerned about getting the wire out of shape, never to be fitted up right upon remount. The attached pics show the carb in the fitted position, then slipped down the posts to the extent allowed by the wire. The sliding down the posts is not far enough for the carb to be removed. I think it needs another 3/8" or so. I though that perhaps the posts could be unscrewed, removed, and then the carb would be free to rotate as necessary to get the Z-connection unhooked. But, even though the posts seem a bit loose to unscrew, they seem "hard" connected. Perhaps the end of the posts have an L-shape, engaging in a slot, and are not screwed into the engine head. I seemed to be at a "chicken-egg" stage. I can't get the carb off, so can't get the numbers to get a G & D kit. Anybody know how to resolve this dilemma? Pic 1 is the carb slid down the posts to the normal postion. Pic 2, 3 and 4 show the carb slid up the posts, with the throttle wire still engaged in the throttle. Thanks.
