Choke and fast idle cam ?
Is the choke plate closed with the engine cold?Ok car is 67 everything is new. 406 short block 10-1/2 to 1 compression from smeding performance.heads are brodix ds heads.air gap manifold.holley 650 double pumper carb. hooker super competition headers.holley blue electric fuel pump with regulator...could be 90 degrees out pump pedal 2 times start car.it starts right up but then you have to keep pumping pedal to keep it going till it warms up alittle.any ideas why it's doing this.or where to look at.right now all vacuum is locked out all vacuum lines are plugged timming is set ar 12 degrees before TDS
Thats half or probably most of the problem. Hook up the vacuum advance and see what happens. I bet most of your problem will be gone. You will have to readjust the carburetor but once you get it dialed in I bet you will be surprised.right now all vacuum is locked out all vacuum lines are plugged timing is set at 12 degrees before TDS
Apparently you have to with this car, so just work the foot a little or get a carb that has a choke.No choke on this one..every other hotrod I ever had pump pedal couple times turn key starts up .couple times feathering gas pedal car would idle and be good.didnt know if jets in carb are to small or anything primarys are #67..None of my other weekend cars ever had chokes either. I never start them in winter or when it's cold so never needed a choke
Not always, when a carb is tuned correctly it should run well even cold. Not arguing with u, cause most of the time we have just deal with and accept it. When a motor is only getting fuel from acc pumps it’s getting none from the idle circuit. Turning idle up won’t help. Everyone so far has been correct, timing, choke, it all matters. You can’t tune the motor if u can’t get out of the car cause you have to keep pressing the pedal.There's alot of overthinking here. Cold engine/no choke plate=throttle feathering till its warm.
