Howdy , My name is Tommy been buildin Motors for over 30 years. The guy that told you about the float and the fuel line is right but there are a few more things you need to know . Hold the float close to your ear and shake it you may hear fluid inside this means it is leaking , replace it # 632019. Also buy a carb rebuild kit # 631029 this will have most everything you need to build a carb right. Replacing the needle and seat is also a must (in the kit) remove the carb from the engine , remove the bowl , remove the hinge pin where the float swings upward and down , watch how the needle is attached and remove it too . down in that small hole where the needle sits is the seat . It's a tiny little rubber "o" ring. You can't see it but it's in there . Go back where the fuel line connects to the carb and put compressed air through it , you'll hear it pop , blow that old seat out . Maybe cup your hand over it and try to catch it so you can see what it looks . If it gets away , no worries # 631021 is the part # for the needle and seat by itself . Sometimes they use a different color rubber , black , white red , green. The new seat has to be inserted back down in that hole , they make a special tool for that but you can use a drift that's flat on the end (not a punch) This is kinda tricky but you can do this all sitting at the table. Look close at the rubber seat you will see a ridge around one side , this is the side that goes up in the carb. So go find a drift just a pinch smaller Dia. than the seat , put some spit on it put it on the end of the drift and push it up in there , make sure it doesen't get hung side ways. Then make sure it's firm to the bottom. That is the hardest part if you made it this far , the rest is easy. Put the clip on the end of the needle , hang it on the tab of the float set it down in the hole , put the hinge pin back in. The float should sit about level while holding the carb upside down. If not , bend the tab easy does it a little goes a long way. If the throttle shaft has any side to side play in it , replace it # 631615 , the engine will suck air past the worn shaft and you will never get the carb to adjust. Some people just don't have the patience to do this kind of work so if you have any questions , call me 865-659-1893 or new carb # 631921 , don't buy after market. Tommy
