I checked the compression today on our 54 truck,after our very first attempt to start it since we got the truck.Of course it didnt start.The compression was about 40psi in each cylinder.My question is .Is 40psi enough compression to get the truck running?Im trying to figure out if we did somthing else wrong.We have spark and gas to the carb.Set it TDC.Should it run with 40 psi?
thank you john
