Following up on my previous post in this thread......
W/o question, my experience as well as others is that TSC sediment bowls are junk. That being said....no sediment bowl will just fill up when newly installed if the carb float is up & the system is air tight.
Put the bowl on & hand tighten the thumb screw. Turn the gas on & look at the bowl. If it starts to fill the bowl, turn the gas off & start over; it has a leak. You will know it's sealed when gas does not flow into the bowl w/ the engine off. It won't fill with the bowl securely on because the float has closed the needle valve in the carb and there is nowhere for the air in the bowl to escape. (assuming the carb bowl is full) When the engine is started the needle valve will open and the trapped air will escape through the carb vent. If you loosen the bowl, it will fill.....and leak.
Do not open the valve more than 2 or 3 turns. All the way open gets you the 1 gallon reserve & that port is usually clogged.
All of the above assumes you have an OEM sediment bowl. If not, I'd get one because a lot of the off-shore replacements never work right & the gaskets are odd-sized.
