INSTALLING HOLLEY CARB

[69 Post Sedan]

According to Eric's thread, https://www.yenko.net/ubbthreads/ubbt...p_spot_a_re_st the blank squirter didn't show up until February of 1970. The date on your carb is December of 1969. So, with that information and noticing that the baseplate is an aftermarket, I would say it's a re-stamp. IMO

Once you install the carb, make sure you don't have any leaks...and don't use Teflon tape or thread sealant on the fuel lines.....it's not necessary. If a fuel fitting is leaking, it's either not tight enough/seated or you have a separate issue (crossed threads for example).

After setting the idle, hook a vacuum gauge up to the intake or watch your rpms if you have a tachometer. The idle mixture screws on the front metering block should be out one to one and a half turns. Screw in the idle mixture screws, one at a time. Try to get the most vacuum or rpm as you can....as soon as it starts to stumble, back it out a little.....do this a couple of times on each side. That should get you started on the idle.

After that, you will have to check/set up the vacuum secondary's. I would YouTube that information.
