Plugged ports on a Hitachi

[djellum]

Hey,

 

so I pulled a ton of stuff off of my Hitachi, it runs tons better with all the cracked valves and hoses cleaned up. I do want to see if you all can double check what I have setup to make sure nothings plumbed improperly. I was specifically wondering about the bowl vent. Im assuming the actual bowl vent is the port that dribbles out gas on the back drivers side. Just want to make sure if it needs to be vented that it is.

 

heres a view of the plugs on the back. the port with the red plug near the middle is the one that dribbles fuel when its not plugged, the lower black one was plugged when I got it. at the very bottom is a hose coming from the firewall that was just plugged into the air box. I can rehook it to the air box, but since I plugged all the other ports on the box I want to know for sure what it is first. its bracketed with the fuel lines (fuel tank vent?)

 

 

This is the front view. most all of these were going to the charcoal canister. the 2 lines that are connected together go to the vac advance, that was how it was setup when I got it.

 

my next project would be the choke. right now it doesn't work at all and just stays open. I like to fix it, or just remove it if its not working anyway, but I need a bit more research first if anyone knows a good resource.

so I wasnt planning on driving till I figured out the bowl vent thing, but I got called into work today. initial findings on the freeway arent good. seems to be getting poor mileage and hesitation, which from reading is pretty standard fair for a bowl vent issue.

 

from reading someone said to plumb the bowl vent to the charcoal canister. another post had the center front port plumbed into the rear one with a tee (red plugs in both pics), which was run to the air cleaner.

 

I guess the question is what is the simplest way to plumb the vent for the carb.
