I found that depressing the intake plate did send fuel to the injectors, trouble is i had it pushed down almost all the way. I had an extra coil so i changed it and i replaced the fuel regulator from my 420, no improvement. Adjustments to the fuel mixture tower dose not give fuel threw the injectors, only depressing the flapper valve will do that. Now this tells me that the fuel body is out of adjustment but for the life of me I cant figure out how that could be!
