when i put the car in gear as i accelarate she feels as if she is going to stall (hesitating allot) so i give her more gas or pump the gas pedal to make her go- what could be causing this? I noticed it's only when i accelarate- when i maintain a constant speed she's fine. that's why i don't think it's a problem with the fuel line or anything having to do with that. My guess would be the spark plugs- any suggestions? thanks a ton!!

The "accelerator pump" in the your carburetor would be the prime suspect. The are several "circuits" or plumbing paths for fuel through your carburetor.
One provides the gas at idle and there are one or two little screws to adjust that.
The main jets provide a certain ratio of gas to the flow of air going through the barrels of the carb. That provides the fuel cruising at a steady speed.
The accelerator pump address the engines greater need for fuel as you increase the revs as you are asking for more power. It squirts in an additional volume of fuel as you press on the gas pedal (one reason that varying your speed, especially doing it often, hurts your gas mileage.
There is a little diaphragm in that little pump that can wear out. A carb rebuild kit ($100) would have replacements for that and a lot of other little pieces. Or you can buy a rebuild carb ($600?) and replace the entire old carb. Or have a shop do that labor for you ($1000?).
The classic behavior of the driver when the accel pump is bum is to rapidly feather the gas pedal to get the anemic accel pump to get enough gas to the engine. As it gets worse, the engine won't just hesitate but will die if you stomp on the gas suddenly.

Acceleration contained in the most user-friendly words is a substitute in velocity, it may both be posative or unfavourable (rushing up or slowing down). some rigidity might want to be appearing on the object to verify that this to take position, inclusive of gravity, friction, the output of horsepower from an engine, etc. So if an merchandise is at a consistent velocity, no it isn't accelerating. also, countless the individuals who answered this question obviously do no longer comprehend the version between % and velocity. velocity refers to a particular route and %. with the intention to have a consistent velocity the object might want to safeguard a consistent route and % ( you are able to't have an merchandise travelling at a consistent velocity even if it is travelling in a circle). a consistent %, certain. yet no longer consistent velocity. In examining a number of the different solutions, i imagine each human being is merely perplexing the region more desirable for you. do not confuse consistent velocity with consistent acceleration, they're 2 completely distinct issues! desire this helps.

I would assume that this car is carburated,if so you could have one of two problems.Most likely it is a vacuum leak on the air intake side of the fuel system,somewhere between the top of the carb and the bottom of the intake manifold,that would explain the "peddling" that you have to do on take off and yet be ok at road speed. It could also be slightly out of time. You may want to check the fuel filter,either one of these could do this to you on a carbed engine.If it is injected,a vacuum leak would have to be my best guess.Definitely don't think the plugs have anything to do with it.

I'd say it was running rich at low idle. It would be tough to get going because of the improper mix at the carb, but it would lean out as the fuel began to atomize and the high speed jets began to do their job. Take te carb apart and clean it thoroughly. Afterwards, read my answer to how to adjust a carb for a string trimmer to get carburetor theory and apply it to your car.

Sounds like a carbueration issue. Might want to have them cleaned or possibly rebuilt. A fouled plug or wire may also be the culprit.

I would first check the timing and for vacuum leaks.
Most likely you need a tune up.

check the inline filter or the fuel pickup
