the primarys are .72 and sec's are .78 so do you think they should be changed to .80 ? as i have .80's
will check the number on the metering block
yes i thnk i have converted from 4150 to 4160 with the addito of the metering blocks.
to be honest i am saving up for fuel injection so if i can hold off i will use the current carb bodies and fit injectors into the inlet manifold. but probably a job when i have some money saved up
