I should be afraid at this point.....
I just took my Holly 850 DP apart and there are two needle screws in the side of each metering block. Counting turns when I took them apart- the tops and bottoms were set differently. What gives? Also the rebuild kit only includes 2 replacement screws. I guess I will have to reuse two of them?
Also the secondary metering block did not contain a power valve, but instead had a plug that is shaped like a power valve. Is this correct? Because the rebuild kit contains 2 new power valves.
