Mark,
Thanks for the info!
It looks fairly simple to drill and tap this area so I will look into that. However Im unclear as to where the tube goes to on the bottom. Is it just open to the air? It doesnt look like this tube brings exhaust gases up but just passes through a port and get heated as you mentioned. But is the bottom of that tube basically just open and the warm air travels up the tube into the choke assembly via convection?
Good to know about the fuel pump. I saw that brass barb at the bottom of the fuel pump "bow" and wasn't sure what it was for. There was an old hardened plastic fuel line that was attached to it. You can see the barb in the first and second picture with greenish sludge around it. It looked like that tube hadnt really been used and it just degraded. I was puzzled as to what it was feeding. Your explanation makes sense though.
What did you end up doing for ignition on your motors? Did you keep the points or do some electronic conversion?
