Norm, in a recent thread, you mentioned that you have converted some Briggs with these primers to a choke system because.you were having problems with the filter housing not sealing properly against the carburettor, rendering the primer inoperable. AVB mentioned they warp and Tyler had resorted to using two gaskets to get them to work.
In other words Sapper, you're on a winner. These Briggs Quantum primer systems can be a problem child.
