Re: Marvel carb
idle speed is kind of a personal preference. On my Marvel I adjust the motor idle speed when the car is fully warmed up, spark advance at about 8-9 o'clock. I then adjust the idle mixture screw. On a Marvel you are adjusting the amount of gas for smoothest idle. This is opposite of a Zenith, which adjusts the air.
Hope this answered your question. |

I could probably spend the better part of the morning reading all that is there. See https://www.rennerscorner.com/slide-show--info.html Check out the rest of their site including gaskets/oversize shafts etc. VERY helpful people. They've forgotten more about 4 cylinder engines than I'll ever know. Joe K
