I am trying to figure out why this fuel log that is on my carb continually leaks at the carb fittings. The fittings have aluminum spacers on them at the fuel bowls....which I am kind of suspicious of.  I am planning on just taking that fuel log off and putting my old one back on as it didnt leak. Here is a pic of the fuel log on the carb.

I had a leak at the same place on the fuel bowl, right where that deadsoft aluminum gasket seals. It turned out to be a small scratch across the face of the seat on the fuel bowl, right where the gasket sits. I dressed it with a small fine file and got it flat and smooth. The leak was fixed.

I figured that getting rid of those aluminum fittings may help it seal better but it also leaks at the very back of that fuel log where there is an allen screw..and it seems no matter how much I tighten it will leak.
I swapped my old fuel line back onto the carb and fired it back up and it does not leak.
But I would still like to try and make this setup leak free.

Did you use Teflon tape?
Nope, I did not use teflon tape on any of the fuel fittings. I have never used any type of tape or sealant on fuel fittings before.

As said check the sealing surfaces and can you toss the spacers, seems like there is plenty of room for the log to be closer to the carb wo any ill effects
