Corrected based on latest info.
Sadly I agree. Some guys luck out and find a good mechanic, but this isn't happening, and probably won't. Truth is, its usually more than just luck.
This isn't difficult stuff, but you have to be willing to do it. It also means investing in some tools - the basic ones will cost less paying someone to do it. Ramps or stack of 2 x 10s, wheel chocks, a flashlight, will let you see the leak. A brass or aluminum bar will be needed when removing the ring. Draining the tank down below the sender is really the biggest PIA.
For basic tuning, yes a tach and timing light would be needed. And a golf tee! LOL
