Thanks again for all the expert advice everyone. I am out of town for the week but will carefully re-read this thread when I get back to the car and report on my progress.
It is the former, it stalls as I am coming to a stop and specifically when weight transfers forward (and fuel in the carb float bowl sloshes around). This probably indicates incorrect carburetor float level. I also know for sure there is an intake manifold leak so I am probably looking at a...
I did not. I will research how to check for droop in the exhaust manifold and add that to my first point on the action plan. For whatever it is worth, the exhaust manifold is not leaking at all, just the intake.
It was surfaced on the big belt sander. The manifolds are straight across the ports checked with a straight edge but I didn't check for rounded edges.
The vacuum leak seemed to be the same before and after surfacing.
That's my thought as well. At first I suspected the carb, but after swapping to a new carb and trying different float level adjustments I am 90% sure the carb is OK.
I have not put a straight edge on the block, but I thoroughly cleaned the gasket area and did not see any cracks.
I have one...
Thanks for pointing that out, I did my best to look for cracks in the manifold and didn't see anything obvious. However, I didn't take it any further than a visual inspection ie: I did not have the manifold magnafluxed. So I suppose it is possible there is a hairline crack somewhere I can't see.
Hi Guys,
It seems I have an intake manifold leak that I am having trouble fixing.
The main symptom I am trying to cure is the engine stalling when coming to a stop. I have a brand new Zenith carb and I have tried raising the float level all the way to the point that it starts to leak fuel...
Hey Guys here are some photos of what I'm working with. Looks to me marked Zenith-1 but I don't know if that is correct for a 1930 Sport Coupe. As an aside, it has been leaking gas out of the weep hole indicated by the pencil - I assume that is the float? I have not had much luck getting the...
Thanks guys maybe I will try another repair before ordering a new/rebuilt carb.
I can weld so I assume I could figure out how to braze it up. The problem is that the crack extends down into the throat of the carb and it was sucking air in messing with my mixture.
I'll try looking around for a...
Hey Guys,
The mounting flange on my Zenith carb top is cracked. A JB weld repair worked for a few months but has since failed again and I think it is time for a new carburetor.
Most vendors will not sell a rebuilt carb without a rebuildable core, which mine is not. I may be able to find a...
Thanks I've had that car for quite a while. Predates the Model A to my garage but not in production!
And I'll give Dick C. a ring this week. Sounds like he's the popout guru. Thanks again everyone, you are all a fantastic resource. Cheers!
That's the deal, it is the Nu-Rex switch. I didn't read between the lines of the description in Snyder's catalog. Maybe I'll start hunting for the correct one now - it sounds like a really neat part.
Edit: By the way you guys are super fast with the responses. Thanks so much!
I did buy it from Snyder's actually. I was under the impression that it would pop like an original. That's a bit disappointing.
Is there anywhere to get a reproduction switch that works like the original?
