SUM-G1420 Adaptor Plate to resolve low vacuum

Summit RacingSummit Racing Verified Purchase

I was originally told by Edelbrock that I needed their wood adaptor plate for their Performer Intake and Carb.. I installed and had a bad vacuum leak because their gaskets in kit were too narrow. I then replaced their gaskets with MR Gasket and it stoped the leak. However I still had low vacuum at idle so I contacted your tech dept and was told I needed your G1420 Adaptor. I installed it and did gain 1-2" of vacuum. I still have low (14") vacuum at idle. I have checked all connections and used carb cleaner around carb base and intake at block. more
