I asked this a few weeks back but the pic i had was lousy, hopefully these are better. Holly NH?
Yes. There should be a name tag in the far side, facing the engine. If it says Ford Model F, it's the same thing.
Thanks Steve. When i pulled it off to clean it couldn't find a tag or any name or numbers on it.
looks like an NH to me! but i dont claim to be an expert
Thanks Nathan,...its nice to know I'm not alone.
Here's where the tag would be if you had one. Note the opening at the bottom of the tag. That lets air get to the vent hole under the tag.
Steve, nothing like that on mine..did anyone make any reproductions of these?
John, the ID plate also covers the vent hole for the float bowl, stops the crud from getting in some-what.
Kerry, is that the same hole that pees out a stream when the float sticks? The thing is that it runs pretty damn good on my nameless carb. What do you use?
John I bet if you look real close you will find the rivets or rivet holes. There should also be a hole under where the tag goes. It is an atmospheric vent to allow air into the float bowl. Without the tag for a cover it will also let in dirt and water. The hole between the tag and the choke shaft hole is an overflow hole. You will notice in the two pics above one of the overflow holes is plugged and one is open. I have seen them both ways. If the overflow hole is plugged, the overflow of a leaking needle seat will have to come out the vent hole under the tag. I do not know why they were made both ways .??? Please let us know if you find the rivets or the vent hole. If you do not have a vent hole then you must have a vent hole between the tag and the choke shaft hole. If not the carb should not work properly ....
I meant to say you must have an overflow hole between the tag and the choke shaft hole. I preview these post several times and I still let stuff get by. arrrrrrrg .. By the way your carb can "pee" out either of the holes ..... if the float sticks
Thanks Donnie, will check it out.
John -- Lang's has the data plate with rivets, but it's pricey: $1.50. It's part number 6200DP.
If you put the tag on with little machine screws (last picture above) it can be taken off for cleaning out the passages.
2-56 screws will fit the holes and the heads are so small they look almost like the rivets. Have to buy a tap that size tho, if you don't already have one.
Somebody correct me ifn I'm wrong, but IIRC that "hole" between the tag and the choke shaft should have a plug in it. I believe that it's part of the idle circuit.
It doesn't make sense to me that Henry would put a vent and an overflow on the carb.
John, if the frame for your carb is aluminum, it is a modern reproduction carb.
