It's probably to prevent cooling weeping into the oil. Vented to daylight instead..

What dizzy is that @Yarb ?

Is that a Bot?

Yeah,,, rust in the transmission wouldn't be my first guess. Junkyard transmission? Flood vehicle? Probably salvagable but you'll need to get as much of that out as possible. Also be sure you have the little metal scupper plate that feeds the rear gutter

Yet...

Cliff, You are not replaceable! C

The needle appears to say M66

These were redone by Steve in either 2011 or 2014. Probably 2011. I can read the engravings. So I would think throttle shaft linkage wouldn't be an issue but they have sat for extended periods of time. I did go through them and clean them when recommissioning this engine

Yes, belt may just need tightening LED headlights would help

So how does damper viscosity affect fuel mixture? No I believe the screws are all the way backed out. I will check. Can the butterflies be shaped to close better? Without adverse effects...

The nozzle must be a 0.090". A 0.092" drill bit won't fit but an 0.087" will We don't have drain plugs

I believe I just laid hands on one of those in the shop the other day...

So Lily is too lean and Cody's car is too rich... I have lower the fuel level 3 times. It is way lower than Steve at Ztherapy recommends. The nozzles are only threaded down 1 1/2 turns. Fuel pressure is 3 psi and the AFR is 10:1. Black sooty smoke out of the exhaust. Ignition is about 10d before TDC at idle speeds. My only ideas at this point is the wrong jets and nozzles or bad float needle valves. Even though they seem to seal when bench testing them. Any other ideas??

I pulled all of the carbs and intake today. This is what the butterfly looks like with a really bright light behind it. @Captain Obvious We loosened the screws and reset the butterfly but it didn't really close up much. The gap is on the top of the bore

When revving the car and dropping the throttle. The mixture goes very lean. Rpm drops to 500-600. Then it recovers back to 1500rpm. Would heavier oil in the dash pots help reduce that? I think they have tranny fluid currently

All good points. I'll keep that in mind. Can the engine pull the butterflies open? I wouldn't think so

Yes, the carb are Ztherapy cabs and have been rebushed. Sprayed the manifold gasket area, balance tube & plugs, capped the booster port, sprayed the carb gaskets and the throttle bushings

So someone check my reasoning: I am trying to tune Lily. The mixture was lean according to the O2 sensor. So I adjusted the float bowls several times. It got some better But the idle is still pretty high even with the idle screws all the way out, not touching. About 1500 rpms. We've looked at the butterflies with a boroscope. They seem to seal pretty well. So I'm thinking "unmetered air". I have sprayed it down with Ether while running and it did seem to increase some around the manifold gasket but no run away leak. We tightened the bolts and it came down a couple hundred rpms, but still not low enough. So I guess I will pull everything off and reseal it with RTV???

You would also need to know exactly where to make them and what rotational orientation...

If I remember right, the gaps I've seen on Gnose cars at the tip of the hood are fairly large. Just like yours...

Has it already been 10 years???

Thta's probably a pittance of what was invested in the car

The second one is the type I have looked at. I'm just not sure it would punch the metal involved. I had a recommendation from Bostitch but they can't even tell me where to purchase the stapler they make... And I haven't been able to find a picture of it

I have done something similar with piano wire. I found the piano wire difficult to fold properly. A paper clip might be softer and easier to fold

That's a great looking repair!
