I just purchased a 1975 2+2 from the original owner who had it stored in his garage since 1985. It has 82K original miles. Silver with red interior. I'm new to the forum but I will post pics soon as I can. We drained all fluids, took down the tank that was 1/2 full of gas (kerosene). Replaced all fluids, filters, battery, and fresh gas. We started her up and she purred like a kitten. 2 problems arose however after we had her idling for a while. 1. She bogs down when you hit 30 miles. 2. Instrument cluster lights are out. We placed a fuse for the cluster but still no lights. What could be the problem? Any assistance will be really appreciated!!!!! Thank you so very much!
