You want to install it with the smooth side out and the side with the ridges in. The neoprene or nylon like inlet valve seat for a Tecumseh snowblower or lawnmower carburetor. Float integrity - check for holes and shake it to check for fuel inside.Inlet valve clip - make sure it is securely attached to the inlet valve and clipped to the float tab.Float height - make sure it is set to specs (it varies from carb to carb - you'll have to look that one up).
Float bowl ring - make sure it is seated evenly all around with no splits.Fuel line - check for swelling, cuts, or cracking.So if you experience flooding or leaking gas/petrol from your lawnmower or snowblower with a Tecumseh carburetor and are looking for a solution, make sure that clip is assembled the right way around. Guess what? No more leaks and no more flooding. But I assembled it again with the pointed end towards the carburetor intake and put everything back together. Looking at it there is no way it could make a difference. He also said that looking at it there was no way he could see how it made a difference, but for many rebuilds where a leaking flooding carburetor was the issue, that solved the problem. He mentions that the pointed end of the inlet valve clip must be pointing towards the carburetor intake or else it may bind and flood or leak. I went online and after going through page after page of useless results came upon this page from JR Combs: It had run well for two days before starting to run rich, then flooding and fuel leaking out of the carb intake when it was shut down. I figured it was either cracked or deformed but when I examined it under a magnifying glass it looked fine and with the carb upside down and the valve seated I couldn't blow through the fuel inlet pipe into the carburetor. I went through the Tecumseh small engine manual trouble shooting section and the found that the of the recommended solutions the only thing I hadn't tried was replacing the float inlet valve needle seat. I had stripped the carburetor twice and replaced all the gaskets and O-Rings in an attempt to fix it with no improvement. Recently the carburetor on my old Wheelhorse/Toro snowblower started leaking gas (or petrol if you're in the UK) out the intake and flooding the engine. If the clip holding the inlet valve needle to the float is not pointed towards the intake/choke end of the carburetor, the needle valve may stick causing gas to leak out of the carburetor intake.
