Help car drops 700 rpm when going from neutral to first gear
New combination 406.
Car drops 700 rpm when going from neutral to first gear and will eventually die. It gets worse when the car is at operating temp. Ignition? Please Help. |

Re: Help car drops 700 rpm when going from neutral to first
Sounds a lot more like carburetor than ignition. Quickest way to find out is to swap another on it. Also, check the power valve(s) if so equipped.

either lock out the distributor or recurve it so it has ~ 20 degrees initial and 16-18 degrees mechanical advance. Easy to do with an MSD distributor.

Re: Help car drops 700 rpm when going from neutral to first
way too big cam and not enough stall but that's not your question.
