I am rebuilding my 4300 DOOF-AD carb for a 1970 Mustang with 351C, 4 barrel heads, AC and Automatic trans. As I was taking the carb apart a small ball dropped out of the main body. I am using a Dayton Parts rebuild kit and neither their exploded view/parts list, nor my shop manual's exploded view, shows this ball. However, the ball is in the Dayton Parts kit. I have an email on this question to them, but I am hoping for an answer this weekend, so I can get the rebuild finished and on the car. It is NOT the accelerating pump inlet ball check (that's straight out of the Ford shop manual). The picture labeled Pic 2 questioned ball shows the ball in question. I believe it goes into an orifice next to the orifice that the accelerator pump discharge valve goes into. The photo labeled Picture 3 show a wooden pointer pointing to were I think this ball goes. The photo labeled Picture 3 is an overview of the top of the main body. If anyone can confirm my thoughts or give me more information on proper placement of this ball, I would appreciate it.
PS. Sorry about the picture label mix-up.
