The temp. is cooler when it runs best.
It sounds like you have a fuel problem because it runs well, then it doesn't. For example, based on your statement above it could be related to the choke. Is the choke manual or automatic? It could also be a problem with junk in the tank or carburetor. If it is, changing the filter might take care of it, or rebuilding the carb.
You should probably post more info like carb make and model (it would also be good to know what type of distributor and advance setup you're working with...ie like jamyers pic above). I would start by posting a pic of your carburetor, so we can see what you're dealing with.

The mystery hose that was coming off my carb base goes into the top of the fuel pump. When I ordered my fuel pump they asked of I had electric or vacuum whipers.....In the car I looked at I could not see that whippers were hooked into the fuel pump. I am now wondering if the fuel pump I have in there is wrong. If I had the one that had the hose to the carb base would it make a difference.
I believe the short answer is no, it should not make a difference. According to the Ford Falcon Six Cylinder Performance Handbook (aka FFSP Hankbook for short, the definitive guide to working on these sixes):
"Some of the early (1960-1963) Falcons used a dual action fuel pump that also supplied vacuum to 'assist' the vacum widshield wipers. From a performance viewpoint, a single action pump from a later model will consume less power to operate."

I highlight 'assist' because it's possible that the vacum hose relayed from the base of the carb to the pump and then to the wipers, but since neither yours nor the one you looked at had the original setup it's hard to say, unless someone else in the forum can tell you the routing (I am not familiar enough with the 170). Main thing is make sure that line is plugged well, otherwise it represents a vacum leak which will only add to your issues.
Sorry for the long post, but it seem like you've got a tiger by the tail. I would not go too many directions at once on chasing this. It seems to be fuel related. While it is definitely a good idea to make sure timing, idle mixture, and idle setting are correct, if you have taken it out and driven up and down hills, accelerating and decelerating without issues, then those adjustments are probably close enough for now. Be patient (difficult for me

) and keep your approach simple and uncomplicated, because most problems turn out to be just that once you track them down. Hope this helps.
