Here is a pic of my six pack unit.
What hoses go to the ports that are not hooked up to anything in the second picture?
Also the engine seems to be flooding, the pressure gauge (see third pic) reads 10psi during cranking. Is this too high or too low?
Any ideas for why the engine is flooding?
Thanks

The big port goes to the middle size port on your three nipple valve cover breather. The little one on the metering block is for the ported vacuum advance.

The 10 lbs of fuel pressure comes to mind. Is the fuel pouring out of the top of the carbs or is the engine flooding? how is your float level?

I have found using the clear site plugs on the side of the fuel bowls are invaluable when it comes to setting float levels and carb tuning a holley knowing when you get a stuck needle and seat,regulate fuel pressure first,with fuel pump on(electric) or engine running if manual pump,I have found trickling fuel out of middle carb and half way up hole on outboards worked pretty good.I check rich or lean at idle by putting fingers over idle bleeds in middle carb.If idle rises lean,drops rich,may be backwards but would have to look thru my notes to make sure but plug the little tube with vacuum hose with a screw in it unless you have operable vacuum advance distributor then put hose to that.Big hose outlet I used to run to outside of valve cover with a fuel filter on it.Always got asked what that was for,(camaflouge) but my six pack had manual linkage and nothing original on it much left when I got it.It is as factory made it almost now.Need to look in archives for best tuning procedures,first you need to get holley rebuild kits if car is new to you and clean them thoroughly blowing out all passages and you will be miles ahead if is a new acquisition,there are experts like Cab to help you.Good luck,I too learned as i went and continue to do so.When in doubt ask,it is usually cheaper too.......

How would I go about getting the fuel pressure down lower? It is a mechanical fuel pump driven off the engine.
Where would the adjustment be??

heres a snapshot of my fuel pump, the fuel pressure gauge is pictured above in my inital post.
Where is the best place to mount it? Does anybody have any pictures of their mounting location?
