‘40 V8 stumbling when accelerating in 1st and 2nd

[mike42]

SoCal……my wipers work pretty good but I may look to see if there’s a vac leak. I’ve got some rubber caps that I’ll try. It only stumbles a little bit now after it’s warmed up. Cruises great and idles great, but it’s when in 1st gear and 2nd gear during acceleration that it stumbles.

Thx for the tip !

Bingo……..the vacuum line into the intake manifold was very loose ! I tightened it up at distributor base again and also at the manifold and it seems to have resolved my stumbling problems ! Thx…..
