I installed the new gaskets from you on my 44pa1 solex carb. After 11
minutes of running, gasoline began to flow over the side between the
bowl cover and the carb body. It looks like the cover might be warped a
little, but it performed before. I’m guessing there is a gap. the bowl
cover you have available is the wrong kind, otherwise I’d buy a new
one. Any suggestions? Use two gaskets? Use some gasket sealer with the
The 1st think that came to mind is perhaps the carburetor is flooding
over (too much fuel getting into the float bowl). That might look like
the gasket is leaking. I say this because I have never seen one leak
out of the float bowl gasket.
- Shake the float to make sure there is no fuel inside. You
can also test by heating up some water and immersing the float. Bubbles
will form if there is a leak.
- After rebuilding and starting up the engine, crud from the
gas tank will rush up into the carburetor and into the needle &
seat assembly. Remove it and flush it out with silicon spray lubricant.
Turn the lit over and blow into the inlet hole. You shouldn’t be able
to blow through. This is more common that you would think, especially
with ethanol around. Ethanol acts like varnish remover inside the gas
- Make sure the gasket in on the seat and that you got the
old washer out. I have made that mistake myself. This would allow gas
to get past the seat.
With that being said, lets discuss the idea that it is warped.
The best way to unwarp, is to sandwich the top and/or bowl between
aluminum, or steel plates in a vise and heat up the middle. Watch this
video about another type of carburetor that illustrates this method.
The last thing would be to try some Permatex Anarobic gasket maker on
both sides of the gasket. Careful not to get any inside and don’t use
too much. A little goes a long way. This is a last resort step and I
have never had to do this on a 44PA1.
