Motor in question: 302/ 650 holley/ no choke/ mechanical secondaries
I understand Holley sets these up for 70 degrees sea level. It came w/
69 and 75 mains, 41airbleed mains and 69 air bleed idle. It has a ?65?
power valve. (the motor pulls about 9" of vacuum at idle - I ordered a
couple of 45 power valves)
Symptom: during a long pull it just keeps getting richer and richer
until it misses (about 10:1 a/f )
Cause: I am at 6600 ft elevation.
Is there a formula to figure the jet changes? Holley says 1 jet size
per 2000 feet. What about the air bleeds?
Or am I doomed to discover the satisfaction of testing until I find a
good combo?????
Thanks in advance!
I remain the dummy from Durango.
