I'm in the process of doing a carb kit when I discovered a couple of problems. First the top of my carb has a piece cracked and I was wondering where to get a replacement, it is the black hard plastic part on the opposite side of the float side. The other issue is the likely carb problem I'm having, there is a little hose inside the carb that connects inside the float and it was in two pieces. I can't find where to buy it or what it is called. This little motor is testing my patience. Thanks in advance for your assistance.
