If this is the "all plastic" float without the bendable metal tab, your only adjustment is to change the thickness and number of small fiber washers used between the bowl lid and brass valve body.  In a recent thread it was pointed out to me that these fiber washers are not even listed as spare parts or available outside of the rebuild kits.  Back in the 1970s I remember all the rebuild kits that included a float valve came with these parts but their use was never explained.  

 

Lacking those fiber washers you may be able to find copper or aluminum crush washers (at your parts store) that can be used to set the float level.  Regardless, make sure the underlying problem is not debris or trash stuck in that new valve seat.  It is not unheard of for old rubber hoses to sluff off bits of rubber when being handled.

Have to agree check everything twice and make sure no BITS are hidden In there...

I assume you mean that you made the washer out of an exhaust manifold gasket.   Regardless, I'm glad this fixed it for you!

Ha didn't read before I posted yup used the gasket not the exhaust would have a bit too much to handle ha😀
