Default Weber Backfiring
- 1969 Boss 302
- 48 IDA Webers
--main venturi 37
-- idle holder 100
-- idle jet 70
-- air corr 195
-- main 150
- Emulsion tube F5
- Runs fine up to 2400RPM
- Belches and backfires on acceleration 2400-3200RPM
- Runs fine above 3200RPM
- Have leaned and enriched the fuel until the cows come how

What is the jet/adjustment fix I need to implement for this problem that appears in the idle to main circuit changeover area?

Thanx much
