I have a Cub Cadet 173cc self-propelled mower from 2006 and ordered a replacement carb for it but the fuel inlet on the carb is smaller than the one on the original carb and it leaks when I try to clamp the fuel hose on it. The new carb came with a smaller hose that will fit the inlet but is not as long as original larger hose to reach the tank. How can I fix that? I tried putting the smaller hose into the larger hose and it doesnt leak but the mower will not start. Is there a special reducer type of connector that I can get to properly connect the two hoses or another remedy? I put a new spark plug in and I think the gaskets for the new carb are in proper order, it doesnt appear to leak anywhere but the fuel inlet when the larger hose was attached of course.
