Going to bring the car to the shop, I need some help Options

Im getting very tired of trying to fix my car my self so I guess Im going to fork out the money and just pay someone to get it running for me. I can get it started by pouring a little bit of gas right into the throttle body but the car won't stay started. I had the car running on 2 pistions not to long ago and I have just replaced a fuel injecter after testing it and finding out it does not work. I have already put new spark plugs changed the oil and replaced the fuel lines but now it just won't stay going. If I press on the gas, once I get it to start it will ether die cause it gets fluided or it will jump up to a high rmp then drop like a door knob. The only place I can find that will work on my car is charging $70 a hour so what do I tell him to fix? Is it my timing or somthing else. My car is a 2.0 1975. Thanks

Thats the thing Im just sick and tired of messing around with the fuel injection system.Im just a 16 old kid who really just wan't to be able to drive my porsche around. The mechanic said he could fix the fuel injection system if its somthing really bad or to make everything easy I can put carbs on it. He said it might be cheaper to fix the fuel injection if its something easy or it might cost lots and lots of money for the other stuff. I just want something to run. The mechanic said he has already done this to 3 other 914's. But tomarrow he is going to take a look at it and maybe its something easy he can fix. And I won't have to buy any big parts. Im just wonderin does $500-$600 sound about right for carbs and labor? Also what type of power will I lose on my car and what about smoothness.
