Grinder,
No, I don’t replace the spray bar, just the plastic nipple housing. I JB Weld the copper tubing to the end of the spray bar.

After you remove the plastic nipple housing from the carb you will see the end of the spray bar. Once you take it apart you will see what I am talking about.

Unfortunately I recently sold all my SSC combat engines to a club member so I can’t post any pictures. I have done this repair to 3 engines total, 2 of mine and 1 for a friend.
