HI club. I was taught that when you first fired up a fresh engine you had to hold the throttle wide open for the first 30 seconds or so.This was done to get oil to the cam.Failure to do so could wipe the lobes (one or more ) off the cam.But I go back to flat head Fords and before Parkising! Its hard to make yourself do it but I've never had a failure on start up.I also rub Molybdenum Disulfide on the cam when I install it.I think it helps but have no proof.
