Nylon Check Ball

Insignificant part deep in the carb and not even shown in the exploded carb rebuild kit diagram or Holley exploded diagram (I only knew it existed because of a passing reference in the '56 FORD manual). I was looking for replacement idle screws and found them only on Mike's site; looking further I found this nylon ball check accompanied with an accurate description of its purpose which confirmed that I needed it (this ball was missing on my teapot carb, probably lost and overlooked in a previous rebuild). It was Mike's description that sold me on this (I bought other parts, as well). Prices fair and shipping ($4) reasonable (and fast via USPS). Mike is available via toll free number for technical questions.
