Question 1923 Witte Model B Carburetor Removal?

The carb is thread (pipe thread?) mounted to the cylinder head and needs to be removed to repair the head. In order to do no harm are there any tricks and/or special tools needed?

I've gotten 2 or 3 of them apart. It's not easy. You need a big bench vise and a pipe wrench that fits the neck of the carb, next to the threads. Soaking helps but is not the answer. The last one I did, I had to heat all that chrerry red and toss it in a bucket of water. After it cooled, I got it apart. Maybe someone else has a better way, but, that's how I've done it without any adverse affects, I could tell.

i just finished doing the same thing today. my trick was a big pipe wrench right next to the head. then clamp it in a vice and heat all around the fiting but try not to heat the fiting it's self. as soon as it starts to turn it should come on out pipe thread is a taper thread so the futher it turns the looser it gets.
good luck chris

I made a tool once for this. I welded a short piece of pipe to the end fo a bar. The pipe was just small enough to fit inside the bore of the mixer. I them welded a tab further up the bar that cought on the resivior of the mixer. This bar was 3 feet long and still would not budge it. I then heated the head red hot. This did the trick. One thing I found out was the butterfly was soldered to the shaft. After heating it up to get it off, the butterfly fell out and I had to fix that.

I had to remove the carb. on my 1924 2 H.P."B" & I put the head in the vice,took the rosebud & heated The head up good & quick right around where the carb. screws in & put a 24" pipe wrench on it right by the threads. It came right out & relatively easy.

Well here are the results of the carburetor removal:

1. The pipe wrench with extension worked without heat. The wrench left some marks but these are cosmetic and fixable.

2. The head had more of a problem than originally thought. Cheesy weld, epoxy coating and rubber cement layer. Looking for a replacement. Note the head was placed on the engine down side up for photography purposes.
