your carb maybe needing rebuilt. you can buy kits to do this at most auto parts stores.
your tstat could need replacing. I would start there , its cheap and should be replaced every few years anyway.

I have to agree with Kem. I had the same issue with an old International Scout I used to have. I final rebuilt the carb and it got better but wasn't completely fixed until I took it in and had a mechanic adjust the air fuel mixture.

Sounds like a float drop problem in the carb. If the float adjustment is off, the float drops either too far, too fast, or both causing a flooding problem especially when you stomp on it.
I'll third the t-stat suggestion.

On the stumbling problem, check the accelerator pump. With the engine off, look down the inside of the carb. Open the throttle blades and you should see gas being squirted into the carb. If it doesn't, then your carb needs replaced or rebuilt. It is possible that it is pumping too much, but usually the diaphragm doesn't work and quits all together. This sounds like your problem to me. As for the heater, no clue with the number of things that could be wrong.

he's right - I was trying to find that term (accelerator pump) but my foggy 40 year old brain couldn't pull it out, and it has been some time since I worked on a carbureted vehicle.
So yes, check it out - you can do what jeep said and look down into the carb to see if it squirts the gas in. Don't do this if the engine is too hot - there is a slight chance of a fireball coming up and hitting you in the face.
