This carb has no name tag but is very similar to a NH s/thru, it has a second choke butterfly made from pot metal, question is if anyone is familiar with it, is it has a hole on the full vacuum side of the throttle butterfly, is it meant to be open or plugged? thanks in advance for any help.

Looks like a Simmons or Wizard. Yes that hole should be plugged,A #10x24 tap and 1/2 inch long machine screw with a lockwasher under the head will do nicely.

The hole was used for an electrical heating element originally, normally not needed with today's fuel (and Australian climate :-))

Originally it had the 6V heating element for cold starting as shown here:




I've been using a Simmons carb for years. Just like an NH it starts easily with the crank. Two pulls up with the choke pulled, key off. One pull with the key on, although it often compression starts when I turn on the key.

I just rebuilt one, NH parts, and put it on my roadster. Quite an increase in power. It also starts easier. Mine came with the electric coil wire. PK

Was this an early version of the Simmons? The coil wire is not shown but the part where the wire would attach is. I did not bid on it but I wondered what it was.

Would the coil wire actually help anything? That's my big question!

I don't see how my car could start any easier.

Several of my older diesel tractors have air pre heater coils in the intake to aid cold starts. Might be something like that. PK

Frank
From the patent No. on the carb. for sale it shows two different drawings for that no and no reference to the simmons or whizzer name.

Bob,that patent diagram is a great help, answers other questions I was contemplating.
