After having the bh off for about 2 weeks, when I hooked it back up the a+b seletor will not stay in the selection a or b. It springs back to the netral pos. Now if you hold it in the b selection the hydrolics work for the bh. with no bogging or anything. not sure what that is. Also my fel is leaking hydro fluid from the brass colored fitting or elbo on right side fel. Any Ideas??
