Hey all so I just rebuilt my carb and am trying to dial everything in. it is a Holley 4160 on a rebuilt 350 pretty stock with an RV cam. I set my idle mixture by tightening until it started to big then backed off a 1/4 turn. Currently I have the distributor vaccum on the front port and transmission vaccum to the metering block. Maybe there's a trans vaccum leak because it wasn't running well when the lines were swapped...is this a normal way to run things maybe because less vaccum at idle with the cam? now when checking timing should I take the hose of distributor and plug it or take the hose off trans? I didn't see any timing change when I plugged where the trans is currently plugged in. with the engine hot and idling in park I should be at -10 right?
