There is a inexpensive way the cycle cleaner thru the injector . Take a look on utube and you will see what I am talking about . I made me one with the syringe and carb cleaner and it works pretty good . I do this to all engines that sit for a while before install to eliminate this problem right off the bat . These ls injectors are bad to gum up when sitting with the fuel today when they sit .

I'll take a look at that. I sprayed them down with Carb Cleaner and then connected each one to the battery with some jumper wires and cycled then on and off a few times to run cleaner through them.
