79 Aisan carb install
Hiya- I'm plodding along on my carb install project and have hit another snag. After scouring the posts for anything carb and vac related, I found this thread which worked out the vac lines in an almost identicle situation. Almost. Evidently, my 79 carb is just differant enough to be a pita. Honestly, I have only a very basic knowledge on carbs and vac theory- I just want to finish my installation.I understand that there will be adjustments,etc but I'm under no deadline.(though I miss my dd) OK- Heres the issue- connection F is different on my carb.Instead of 1 line coming out, I have 2 vac ports there.It is either that,or that one port in the middle replaces F.None of these connect to the down angled port which the 78 carb has ( connection F).
If I have gathered correctly,all the connections I need are as follows:
1. vacuum advance from dis. to connection G
2. fuel in- connection J
3. switched power to fuel cut sol. E
4. my missing F connection
I have capped all else, w/ the exception of 2 ports on insulator block.Can someone help me work out that F connection? Thanks to Trollhole and co. for the excellent thread I've been working from. (the diagrams were most helpful)
A- capped. There is no large outer vent hose on a 76 canister.
B- capped. EGR inlet to carb
C- choke breaker. connect to vacuum fitting on intake manifold in front of carb. Remove TP linkage.
D- remove.
E- ICS- connect to stock carb wire.
F- HIC. connect to vac nipple on PCV fitting in side of intake.
G- distributor vacuum advance, if so equipped.
H- cap
I- cap
J- fuel feed
K- fuel return. Plug if using 79-newer pump.
