I have some good news. My original carb is going thru the rebuild motions and getting close. Bob the Holley guy said he had extra butterflies. So he cleaned them up and installed them. Got the ones with the holes out of there. He also bushed the throttle shaft and installed the Holley #125-500 Kit. Which is the power valve saver. Comes with 2 springs, two balls, and two keepers. Also the bit and stop for the bit. He said he will check for warpage etc. He is going to test it on his neighbors '68 Camaro. So hoping to get it back soon, I am thinking by the weekend, or on it.
The after market 4150 I had bought, I sent it down to Florida. That is the testing place carbs with issues go. At least from Specialty Parts Direct. Here is his latest email.
Hello Dan,
The carb has been corrected and is ready to ship back. Can you send me your UPS address?
Craig did experience the problem and ended up finding the holes in the front metering block that supply fuel for the idle were too large and causing the carb to run too rich. They were like a jet so he replaced them with the correct size and made all the other adjustments. He then ran the carb for a while again and said all is good.
Thanks,
Mark
So that should be here Friday or Sat. So after weeks and weeks with no good carb.... I will have both back probably with-in a day of each other. Go figure... Maybe I will be able to take a spin this weekend... Danny
