Reply to "Holley carburettor adjustment needed"

dipascaleMember

Thank you Doug and Patt for the information of vacuum value 16-17 in, on my side I will recheck the advance and a possible air intake because on my new Holley 4150 (0-4779), I had problems when opening the secondary, I had backfires in the carburettor, the needle under the secondary nozzle was glued (storage too long?) and the gasoline did not come out or little from the nozzle, I may be damaged the pcv valve or other, I will recheck all that.
