Ok, so i put new gas and new plugs in my 97 Mach 1 and it still wont start. I've been looking at the fuel lines and have noticed that there is air bubbles in them. I've pulled it over numerous times to try and pump them out but I still cant get rid of them. Does that mean my fuel pump is bad? Also how do you reset the float heights, and does anyone know what number the jets should be?

Remove the plugs and smell them to see if there getting fuel. Also check for spark.

Air bubbles in the fuel lines mean there is an air leak in them somewhere. Since it's not expensive, go ahead & replace the lines. They are probably very stiff going on 10 years old. Old lines can crack/split & develop air leaks at the fittings. Be sure all clamps are snug, as well!!

Yeah i've cleaned the carbs and made sure nothing was in the jets. I've read a couple other threads and came the the conclusion that maybe the pump is bad so i ordered one and when i get it i'll replace all the fuel hoses as well as the crankcase hose.
