I sprayed water all around the carb and the intake and the idle didn't fluctuate. I will be replacing the valve covers soon to eliminate the extra breather and then Im going to try redoing the timing and carb adjustments.

It should be at 15 before tdc

My block is a 77 but I really don't know how much of my engine is in its original configuration. It's in a 55 Plymouth with lots of custom fab all over. From what I can gather I believe a lot of the parts used probably came off of a Dodge truck. I don't know if any of that is helpful information...

I don't know my cam by the reason I'm hunting for a vac leak is that I have idle in park all the way up at 1000 and In gear it drops to the 5 to 7 range depending on if it's warmed up

Ill try this out

I do but I have a one inch spacer for heat soak on there

Well I didn't want to run it like that but I was trying to see if my vacuum leak went away if I either (A) just ran two opposite breathers, or (B) ran it with pcv one side and breather on the other. I couldn't do option b because I had nothing to plug the breather hole with at the time. I'm just...

I have a 77 360 with a Carter AFB style carb, headers, and performer intake, and I believe I have a vacuum leak from my breather caps/ PCV setup. Currently the passenger side has a breather AND the PCV valve and the drivers has a breather. I read that there's not supposed to be a breather on the...

Thanks for the schematic, what's the NO tab on the vac switch? Before I started trying to set it up right it had the wire on that and not NC.

Should They have a wire running from the other tabs as well?

The od does kick in by itself

Okay I got some pics and it looks like they're marked so that's nice would these switches be running off of vac pressure or the trans pressure?

I bought the car with the combo and this whole time the switch was sitting there without a vac line connected. The overdrive has always worked though, and I will try to get a pic of it there are pressure switches on the side of the transmission

There is a kickdown cable but again I don't really know much about this so I don't know if that answers your question.

Manually downshift to second? I don't understand I guess. I know very little about the transmission end of my setup honestly but what would I be looking for to answer your last question? Also it might be important to note that there's two drive gears, O and D and when I got the car the guy...

I have a vacuum kickdown solenoid installed on a 360la a500 overdrive combo, (got the car set up that way) and I'm wondering which vac port to run it to. Here's the solenoid The idea behind this (I'm told) is that during normal driving, it would go 1, 2, OD. But with this hooked up...

I'm not sure how to find out I, but also I'm pretty sure this switch is custom

I discovered that there is a vacuum kickdown solenoid that appears to be wired up so I am wondering firstly where I should run the vac line to it. Trans is an a500 overdrive, engine is a 360 la, and the carb is a Carter 625 cfm. Heres a pic of the switch I don't know for sure if it's hooked...

Just the angle it's a squarebore

Okay so I've taken it off and apparently both of the ports for the primaries are above the plates. I did see light through the driver's side passage so it isn't blocked. You can see the line where the plates are closed is above the ports. And this last pic above is with them closed... So I...

Is the port under the choke mva as well?

That's what I'm thinking but I will confirm either tonight or tomorrow with pics

Yes this is how I have it set up, but I have a suspicion that port isn't drilled in the manifold vacuum port.

Maybe not the most practical, but definitely very symmetrical.

I will give pics of where the ports should be when I take it out again but here is a couple photos from when I rebuilt it

Yes it's the correct side that I'm checking and the other is ran to the distributor

This might be the case since it's for a marine application... I've seen some diagrams refer to that port as an EGR? Port On marine carbs.

Well I will try the carb cleaner but if not then I'll take the carb off and see what's going on with that port.

If it is plugged; would that be debris or something done by the manufacturer since it's a marine carb? If it's like that from factory is there anything to do about it or should I be in search of a normal carb?

1-The needle on the gauge doesn't even move at idle at that port but at the choke port I believe it was around 15 inches 2-ive been hunting for a leak but I've been unsuccessful so far in finding it. Would a mild leak cause it to have 0 vacuum at the port though? 3-its possible it's blocked, is...
