1965 Valiant slant-6 225 carburator
Update on the Ford Granada carb on the 1965 Valiant... with a question about vacuum connections.
Referencing the below picture.
A: PCV
Damn, I hate this connection. If I hook it up, it's like bad vacuum leak and the car really hates to idle. If I disconnect it (and cap the vacuum connection on the carb) it runs great. I've tested the one-way valve. And I think the filter-cap thing is ok... I'm wishing the PCV would not open until 1000 RPMs or something... is that a thing? That would solve my issues. Ideas? Opinions?
B: float vent.
Presently I've connected this to the air-cleaner. I was nervous that such a connection would lead to a lean condition because it's a mild vacuum... but I haven't melted anything yet! I did have this routed to a meandering hose (like the carb vents on my snowmobiles). That worked fine, it was just ugly. I notice not difference in performance either way... I think the vacuum on the top-side of the carb is weak enough that it doesn't really matter. (Of course i don't have EGT or an oxygen sensor, so... hope I don't burn down.) Opinions?
C) boost valve
I just connected this to the same vacuum a the vacuum advance. Different size hose, so I used a 'universal' vacuum T-connector. I don't see any issues with this.
D) Just a hose going to the vacuum connection on the Carb
E) Distributor Vacuum Advance
So.... This was *not* hooked up when I bought he car. The connection (D) on the "original" Motorcraft 2100 was capped. I've tried it both connected and disconnected and I really don't notice a difference in performance. (When I disconnected it I obviously capped the corresponding hole in the T-connector.) I'm nervous that it was disconnected for a reason. I'm thinking if it's connected it could mean the timing is advancing too much.) I suppose I should get a timing light on the damn thing... I found the marks on the on the pully... but the marks on the block side are a bit ambiguous so I need to find TDC to be sure that I know what I'm looking at. Thoughts?
Thanks,
Joe
