Oil pressure is really low

Bipass the heater core and check the hoses to it for blockage, that could be your part of your over heating issue. Sooty plugs is carb jetting issue, choke is staying partially shut making the mixture too rich or timing (fuel not getting completely burned). Yes I know you got a new carb, but that does not mean it was tuned for your engine. Backfiring thru carb AND exhaust means your timing is jumping from advance (carb) to retarded (exhaust). This will also affect the engine temp., retarded timing causes temperature to got up.

I haven't changed the plugs since putting the new carb on. I just wonder if I put a new set of plugs in, if it'll fix the problem. I am missing a piece of the carb that goes to open and shut the choke any way. I have looked around for the piece on the internet and have had no luck.. What could be causing the spitting and sputtering.
