Vacuum question
Took a 2 bolt timing cover of a 59 engine. The distributor was a 21A, crab. The 59 had double sheave water pumps so I assume it may be a truck engine. In the vacuum inlet on the timing cover was a brass plug with a washer. See photo.
What would be the purpose of blocking off the source for vacuum to the distributor brake ? |
