Hi Gents. First post here. Just picked up a '77 Freeborn Red 40 that had been sitting for probably 20 years. Its in good shape body wise and has, like all 40s potential. This is my second 40. I owned a white FJ40 1980 in college. My main focus is to get it running and enjoy it. I also want to work on it with my kids and slowly restore it. After soaking the motor we were able to get it to turn. I changed the oil and filter and we got it to fire with some carb cleaner today but we are not seeing any oil pressure on the gauge. It would only run for a few seconds. Any suggestions to verify its getting oil pressure or does it need to run longer than that for the gauge to work? Thanks in advance!
