I needed to replace my carb. I went to O'Reillys and bought a Tomco rebuild. It was a mess. The fuel inlet gasket was leaking fuel. I replaced that. Got it back in the truck and both main gaskets were leaking fuel as it was warming up. I took it back. They replaced it. Took the new one home and the fitting on the bottom that attaches to the intake is a completely different size. So, I take that back and asked for my money back. Now I'm at a loss. How do I know the next one that I purchase is the going to be the right size and not leak every where. Arrhhhh.
