JD carb fix.

[aametalmaster]

I got this 1938 JD carb from a customer and the threads were shot where the float bowl nut screws on. The bottom 3 threads were stripped off. So after pondering how to fix without welding i can up with this. I bored a stub of metal for a 7/8-18 thread to match the existing threads and made sure it screws on tight since there were good threads on the upper part. I threaded it with this custom ground HSS threading tool since it was against a sholder on the inside. Took 4 or 5 passes and it fit great. The black line on my tool bit is my depth stop. Then i threaded another stub 7/8-18 OD for this adaptor to screw onto to thread the OD and trim to length. Then i will make a custom 1-18 acorn nut to replace the old 7/8-18 and it should be fixed. To be continued and more pics to come...Bob
