RE:...

cheap way : pour 5 bottles of injector cleaner an run it through while driving,

$$$$$ way get precision tune to pressure clean them,


i think you largest problem is the muck and rust in the gas tank, sitting that long its bound to bad,


there is screen in the tank to protect the fuel pump from debris, but the problem is the screen clogging up,

 

Dude= if your tank is anything like my 240, and I'm sure it is, there is a sprayed on lining inside that turns to tar after the gas sits in it for years. Get the tank cleaned at a radiator shop asap !!!

 

You can also contact www.rceng.com (rc engineering) and I heard they do excellent and quick work in cleaning injectors.

 

buy some sherco

injectors. cheaper than cleaning. 106$ for 6
