My grandpa left me a 1972 Cadillac Fleetwood Limosine. It was parked in his garage for 10+ Years now and Ive always enjoyed the memory of this Huge cars sound and size from when i was young.. Ive never hot rodded before, but Im pretty swift at figuring things out. Im not sure what route to safely take first. I have a few questions. 1. Old Gas. gummed up Carb. how to clean bowls, refresh gastank in the least invasive way to avoid (if possible) damaging seals. 2. damaging the cylinders/bearings due to the possibility of rust in the engine. How to check internal conditions* oil is dark but looks clean. 3. troubleshooting the No Spark issue. Im going to buy a semi truck battery tomorrow Lol and some fogging oil... Just hoping you guys might know a few good places to start. how do I drain this gas tank.. siphon?
