I have a Husqvarna riding mower LRH125. Took apart carburetor and cleaned and put everything back but cannot see where to attach the green ground wire that is attached under the air filter. Where is that attached to the mower?

Hi,
Because of the model number I gather this is a single cylinder engine. Behind the carb there is sheet metal that directs the air flow across the cylinder fins for cooling and away from the carb to prevent heating it. Looking directly at the carb there is usually a hole through the sheet metal, a cast boss behind it with threads just to the right, or behind the carb and a small screw about 1/2" in length and with a 5/16" hex head goes through the eyelet, the sheet metal and into that boss.
Peace,
Clarke
