So, I have been tooling around town in the 68' Datsun i recently got and i have a few noob questions about it running. I figured id put them all together to avoid tons of 1 reply posts. So without further ado...
Q1: I dont have a temp gun so I have to rely on the dash gauge. What is considered "running hot" vs optimal temp? When going around town, the guage reads at between the second line and middle point (covering the thermometer logo). On the highway, this gauge reads at the half way point. Is this considered good? From what i know, it is running the stock radiator which has an electric fan attached rather than the old engine driven one.
Q2: on a related point, when the temp gauge reads at above the second line but below half way, the car is prone to mis fires (a few revs fix this sometimes) and when warm (half way mark) it seems to have problems idling and on occasion has died. Im taking it to the shop to see if a carb tune can solve this and push off a carb rebuild for a bit or if its futile. I do know one carb runs rich and the other runs lean which probably doesnt help things.
Q3: most of the people I talk to seem to let their car idle for several minutes when starting cold until the needle hits the second mark on the temp gauge. Recently, i have been running for about 30 seconds with choke and 30 seconds without choke and once the engine idles normally, i take off. This is my first carburated car so... what do most of you do?
That's mostly it for now. The car is in a pretty rough shape for its overall condition when i got it, so i dont entirely know what is "normal" for the car and dont want to do any additional damage that could be solved by some knowledge. Any insight to this would be awesome!
