All, I am working on a 1983 honda shadow that I have been working through some bugs trying to start. Took carbs off and cleaned, new gasket and float needles, new fuel filter, new fuel pump. The bike cranks and no abnormal noises. I squirt some oil on top of cylinders. changed plugs (didn't have NGK so put champion or something that cross referenced). Have fresh fuel in reservoir tank, don't have tank on bike for trouble shooting purposes. Jumping fuel relay wires. Pump clicks then stops. Carbs were awful, cleaned jets. Did not pull out air screw (had not been drilled out). This bike is all original and has been garage kept for many years. Me and my dad rode the bike to the great smoky mountains when I was young and I have a trip planned for end of august to relive the experience. My dad passed in January and want to get this baby back to it's glory days. My theory is that I am not getting a strong spark. Any help appreciated.
