How Do You Replace Lead Fuel For Old Cars?
Older cars may seem simple in comparison to today’s modern masterpieces, but they are much more complicated than you might think. Take the fuel system, for example. The cars of yesterday were designed to operate on leaded fuel and at much higher compression ratios. The fuel of today contains no lead–thus it serves up problems in those older power plants, especially in the form of valve train failure. The remedy? There are a couple of areas where you can improve older vehicles and the use of today’s fuels. Park the car on a flat, level surface and apply the parking brake. Open the hood. Adjust the timing. Running an older engine on today’s fuel requires the timing to be retarded a few degrees. Mark the harmonic balancer with chalk on the indicated number of degrees you wish to set the timing at. (This will be an experiment for each particular vehicle, but shoot for 10 to 12 degrees timing from idle and 34 degrees total timing). Loosen the distributor hold-down bolt with a wrench just e
