Have a few issues. The adjustment on the bottom of the carbs that I think must push on the needle valve diaphram. How far should this be adjusted? Its a basket case sled and I am not sure if I have the right wires on the coils. The wiring diagram I got off the intenet shows orange and gray wires to the coils. Problem is I have two oranges and two grays. Is there a good resistance reading I can check to see what wires are right? Seems to be that I am flooding it out yet I have spark and the carbs are clean. Maybe spark at the wrong time ? Maybe carbs adjusted wrong? I have the smaller adjustable mixture screw 1 1/4 out and the bigger one 1 turn out as per another website. 120 PSI both cylinders. Any and all help appreciated!!!
