Yay ! . Now , try opening up those plugs to .040" and see if it doesn't run even better...
I use copper cored plugs as those newfangled platinum etc. plugs all run too cold & foul easily . I'm still driving and loving my new '69 C/10 Stepper , yes the engine is worn out so it burns a quart of oil every 150 + miles but , due to careful tuning , it also runs strong & returns 17 MPG which for any old truck , is fantastic . I also discovered that it smokes & burns far less when I use 20W-50 oil than it does when I use my beloved 10W-30 or 10W-40 oils =8-^ . You have to feel your way to each engine's " Sweet Spot " & keep it there . 17" steady vacuum @ idle is terrific . -Nate Ken wrote: > > Hi Nate. > Back on the project since wednesday. ] > Still having low compression on one cyl.
